DIY Remineralisation for RO or Rain Water

 Share

Recommended Posts

Thank you so much for the feedback. I was hoping I was finally on the right track with minerals as I've about exhausted every other avenue at this point. I hated science at school & now I read papers trying to figure out water lol

 

Ok - the rainwater tank for collection is not metal nor is the 140L bucket :) I know that the water will leach copper from the pipes in this house which is why I use the Cuprisorb in the prefilter water. The copper readings were only just readable but I didn't want any reading so that's why I prefilter it. I have done some testing to a small degree for some metals (like copper) but no laboratory testing has been done. I did send away for a well water testing kit from the USA & it contained kits for many things but they were once only usage so I don't have them any longer to know what they were precisely. For all intents & purposes it suggested that both the rainwater & groundwater are of similar quality & local irrigation guys have told me that the colour is tannins due to where I live. I don't drink the ground water but I do filter it for the fish. They actually seemed happier in that water than rainwater in my opinion but rainwater is what comes out of the taps for now so thats what I use.

 

It has also been suggested that I start raising brine shrimp as food for my fishes to help with mineral replacement, would remineralising negate the need for brine shrimp? Or are they still a good home grown feeding alternative? I stopped using frozen foods a while ago as the quality at my LFS was poor (they been defrosted & refrozen, trays half full, etc) so all I have had access to locally is dried foods. Even brine shrimp eggs here are sold in large quantities only @ $99 or so - wasn't keen to invest that much but Aquotix has much better pricing.

 

Once my shrimp start to improve in health I will try & get some photos - my low ph with remineralised water should start improving their colour too if I recall correctly, so I am looking forward to a return to a happy, breeding & thriving colony :)

 

Finally, I must say - you guys answer here much faster than I've ever had a response on any fish forum I asked for help at :) I think I might get to like it here :D

remineralising is not a replacement for feeding nutritious food. Definitely do both.

Brine shrimp are good for fry and small fish, but worms would be more nutritious.

I saw Techden stocking freeze dried blackworms, you should get that. It's dry, and won't need freezing.

Ahh, thank you for that information :) I will bear that in mind & improve their diets all round. What is best to feed cherry shrimp? I don't get the best advice here in Bunbury and usually get told to buy whatever the LFS is selling. I do prefer to purchase the more expensive foods hoping that they are also of better quality. However I am yet to be convinced that what they sell is the best food for my fishes & shrimps :)

You're welcome.

If you are already purchasing stuff from TechDen, or The Age of Aquariums, check out their list of shrimp foods.

They stock some good brands of food. Like Benibachi, Genchem, and Shrimp Crack.

Bundle up your purchases and only pay $7.50 for shipping.

 

Alternatively you can get Shrimp Crack from Boss Aquaria, the original creator.

Everyone who has used Shrimp Crack has reported their shrimps loving it.

Kinda confused with your question.

You can use this for CRS. Or any other shrimp for that matter.

But it's technically not really the answer. 

You use re-mineralising solutions to remineralise Reverse Osmosis water or Rain water or very soft tap water, in order to get it to a target TDS for whatever shrimp or fish you are keeping. This target depends on they type of shrimp and what their preferred water parameter requirements are.

 

If your high grade CRS likes 140 TDS, then mix just enough of this into your RO or rainwater to get it to 140 TDS. Measure it with a TDS pen.

If your Cherry shrimp likes 160 TDS, then mix enough to get your RO/rainwater to 160, again measured with a TDS pen.

 

You don't pour a whole lot of remineralising mix into the tank and it automatically adjusts itself to CRS ideal parameters. It doesn't work that way. You still need to test and measure. <- this goes for all remineralising products.

 

Therefore, while it's good for high grade CRS, it's also bad if you use too much. <- this goes for all remineralising products, not just my DIY mix. The trick is knowing what TDS your shrimp will like best and adding just the right amount to achieve the correct TDS reading.

This mix helps you raise TDS, since using pure RO water or rain water is detrimental to fish or shrimp in the long term due to the lack of minerals in that type of water.

 

Hope you understood my response. I didn't know what to cover, as I didn't know how much you knew about remineralising products.

actually i also want to know, how did you come out to those ratio of mineral? if you dont mind me asking

is it by trial and error?

 

if i want to house RCS for now and later wants to change to CRS or maybe higher grade CRS, is it okie if i dobit by bit water change to this Remineral RO water mix for every water change? I am currently doing a aged tap water cycle to my tank, and the water is kind of hard in canada but okie for RCS cuz I breeded some years before with the tap water here.

 

or its better sucked out all the tank water and changed all to these remineral RO water mix and do a drip method to add shrimp back to the tank instead of water change bit by bit in few months or within a year until i reach the TDS level for CRS?

 

sorry if i have too many questions, but i am kind of suck at science :unhappy:

Not really trial and error.

A bit of science behind it. The final ratio was fine tuned was after a bit of trials. There was no error though  :lolu:   :anyone:

 

Well if you are planning on housing RCS with CRS in the same tank ...

I would start the tank of with parameters that will suit CRS right from the start. 

RCS can get used to those parameters. Always drip acclimatise any new shrimp when adding them to a tank, even when you think ph, TDS, GH/KH match. There are a whole lot of other parameters to match apart from the common ones.

 

If you change to RO water later on, then you can do it at each water change, which is the least stressful on the shrimp or, in one big bang, then drip acclimatise the shrimp back in.

Hey Killer, check out the pinned articles by BlueBolts and JayC in the water parameters section. The ratios are mentioned there and JayC has supplemented that information very neatly in his articles. The ratios were probably already established - Hagen's (Nutrafin) "African Cichlid water conditioner" and Seachem's "Equilibrium" both provide Ca:Mg at the same ratio. 

 

RCS really prefer harder water than CRS so it's not normally recommended to keep them together. If you will do then manage the water for the CRS as the Cherries will adapt better. If you're not keeping the CRS yet then a slow change to the new parameters is probably fine. 

 

Beat me to it JayC! What he said Killer.

Is there any reason that your DIY Remineralisation mix couldn't be used for fish as well? 

Obviously you're not going to have tested it on every type of fish conceivable to be 100% sure, but I can't see any reason why it wouldn't be OK for most (if not all) species?

Of course it can be used for fish.  :thumbsu:

I don't recall saying that it can't be used for fish. If I did, apologies.  :phew:

In fact, I use it to remineralise rain water for my amazonian biotope fish tanks.

And for my Killie fish tanks. 

 

It doesn't matter what fish or shrimp. You just use as much or little as needed to get RO or rain water up to the right mineral content specific to the species you are keeping.

I keep my Amazonian tanks at 80 TDS.

Killie tank at 140 TDS.

Shrimps 150 TDS.

Hey jayc

does that imply that ca:mg ratios are same for fish and shrimp?

Check my post above. Hagen and Seachem both have plenty of resources for R&D and have developed products with the same ratios that are not specifically intended for shrimp. 

 

The Hagen product supplies Calcium as Calcium Chloride due to solubility and price reasons, and you'll find that most conditioning salts do too, including others from Seachem. Because Chloride (and Sodium) are not desirable for planted tanks and also not typical of soft water environments, "Equilibrium" uses the sulphate forms, the same formula that JayC described.

I will add that it's just more important for shrimp due to the moulting issues they can experience. While fish and indeed all animals need Calcium, Rickets (bone deformity due to insufficient calcium supply) has apparently never been observed in fish. 

I'm sure Fishmosy could add some technical detail to that statement.

Sorry to jump in and change the subject. i was looking for this product Hagen's (Nutrafin) "African Cichlid water conditioner". Anyone know where I can get a bottle. My googling skill have failed me

 

Dw I found it.

not at all Jay, you didn't say not to use it for Fish, or even remotely come close to implying it! 

I just wanted to check with those in the know before I went ahead and did it, call it a 'stupid' question to avoid a potentially very stupid mistake.

If I remember correctly potassium will raise KH? If so have you found any issue with CRS/TBs ect. Most, if not all sites recommend 0 KH for Caridina. 
 
I like the sounds of your mix over saltyshrimp and the benefit to the plants/mosses sounds like a bonus and if no issues with raised KH, the water/PH stability a bit of KH would bring would be a good thing.
 
I am a bit hesitant to change my Taiwan Bee system over to it, but would like to if you (and others) have had good success. Are you using the mix with TBs?
 
Also, a bit off subject. Do you know if all these minerals (from Aquotix Aquarium or Aquarium Online Store) are food grade? I wonder if this mix would be good for re-mineralizing RO water for drinking. I use a re-mineralizing cartridge for the drinking tap for my family but I believe the cartridge says "dissolves Calcium Carbonate into the water. This adds minerals for good taste and health and neutralizes the pH" hardly sounds like healthy water to me. re-mineralization mix sounds like a better option or should I just stick to taking a mineral supplement/pill (hard to get the kids to do!)

Aquathumb, yes potassium itself will raise kh. The last time I checked my tanks, KH took 1 drop to change the API test. I wouldnt use potassium if there were no plants in the tank. But if you have some plants, they will use K up very quickly.

You can always reduce the potassium amount a bit more or remove it completely. Thats the beauty of diy mix.

You'll have to ask AOS, if those minerals are food grade. I doubt it, as they would have said so. Food grade would also cost more.

I use Potassium Bicarbonate to raise the KH but I'm not sure how Potassium Sulphate is supposed to achieve this?

Hey JayC, I'm on my way out to buy a bunch of this stuff and i have a question re making the mix up and storing it. 

Is it a viable option to mix say 10x the recipe, dump it into a sealed container, shake the crap out of the container and then use it from there with the occasional shake?

      I believe the rocks are banded jasper. Previously when I first set up the tank, I was worried about the rocks. I have done previous testing with them before. I don't have hydrochloric acid but I've done the vinegar and water soak test. I had a test rock in RODI for a month with no change in GH and KH. There were no reactions to vinegar. The rock was marketed for aquatic use but it doesn't always mean it's correct. Sometimes I do question it though. I previously moved some rocks higher out of the substrate to help fix the scape and there was a dividing line in the color of the rock. The portion originally above the substrate had darkened and the part that was previously buried in the substrate stayed it's original color. The only other thing that comes to mind is that maybe I have been overmixing my re-mineralized water. I could have sworn that when I originally made the mix to 180 TDS in 1 gallon of water, it was 6 GH and 4 KH. I did some mix testing yesterday and at 160 TDS, it was 6 GH and 3/4 KH. I did a 10% water change and replaced it with straight RODI water. It brought the KH down to 5/6 but GH also down to 5. I will do another 10% water change next week and probably add in mostly RODI and a little re-mineralized to keep calcium and magnesium content in the water for the shrimp.   I think the KH rise could have been part of the issue. If I recall, I saw a shrimp laying around and twitching, like I've seen in a failed molt. The higher KH had totally skipped my mind and I went straight to thinking it was a food issue due to the ton of shrimp in the tank and light supplemental feeding. Though maybe it can be a contribution to possibly shortening their lifespan.

      The copepods are only really a problem as they compete with the shrimp for food, and look unsightly, but are actually otherwise a good thing and indicate the tank is good! As mentioned by JayC, I had success using fish, they wiped out the infestation in a couple of days. Every environment will find its 'maximum occcupancy' level based on how many it can sustain, and this can be increased with additional food but thats a difficult balancing act to get right. If the filter is clearing some of the copepods, then it will almost certainly also be clearing some of the new born shrimp (hense the decline) as they are similar sizes, rarely do you see newly born shrimp as they are soooo small. I would do as JayC recommends and change the substrate, but would also add some nano fish and plants as it is quite a big tank? Most substrates have some sort of run-in period so this may mean putting the shrimps back in the old tank for now? Shrimp don't need hiding places, unless there is something that predates on them. If you want to try the fish route then sufficient plants/cover/hideouts would be recommended to maximise the survival rates of the shrimps. If you do use soil substrate with plants you don't need additional plant fertilizer as the soil and shrimp waste will cover that.

      The KH is to high for sure and should be reduced, as JayC recommends. Best way to check the rocks is to put them (individually) into a container with pure RO water (which should be zero on all reading) and test the water after a week to see if it has stayed the same parameters. Water changes, slowly added is the only route I know of to reduce the KH! Other than that, everything you are doing etc seems to be well informed! Are you convinced there really is any real problem (other than high KH) as shrimp only live 12-18 months anyway so it could just be natural life span with the high KH also contributing?

      Copepods themselves don't pose much of a threat to shrimps. Apart from out competing the shrimp for food. They would be eating the same foods as adult and baby shrimps.  Copepods can be unsightly in a tank, especially in plague proportions. Unfortunately anything that will kill them will also kill shrimps. The only method that I have had success with is to catch all the shrimp and start a new tank. Do not reuse the gravel, plants or filters. Nothing from the old tank must move to the new tank. The shrimps are caught and placed in a temporary tank/hospital tank, for a few days while the new tank is set up, and then caught again to be placed in a new tank.  It's pain for sure. Oh, another method that works is to add fish! As long as the fish are shrimp friendly of course.  High Nitrates can be an issue for shrimps and shrimplets. So I would put this high on the list to remedy. High Nitrates is linked to detritus. See below.  Heavy amounts of detritus is one of the causes of Nitrates. Detritus that has sunk deep into the gravel, and stuck on filter media can be the causes of Nitrates increasing. When was the last time you gravel vac'd? Or the last time you squeezed out your filter sponges and cleaned the filter media? Of course, cleaning media should be done in the old tank water. Never clean filter media in chlorinated tap water. Lots of fast growing plants also help control Nitrates.  Do you still have the old 40 tank? I would use that as a temp holding tank and move all your shrimp across while working on the 180 tank.  Sand, even if it's black blasting sand, can get compacted and trap detritus. I would look at replacing it with substrate that has a similar shape to ADA Amazonia. That round shape has a reason. It allows more water flow between and as a result is "lighter" and easier to clean with a gravel vac. Plant substrates also have other benefits like holding more nutrients for plants, easier to plant with and has pH buffering abilities.  Yes, that is an increase in costs, but I have never thrown out old ADA substrate. I use it new in my Caridina tanks. And when the substrate has lost it's nutrients and buffering capabilities, I wash and re-use it in my Neocaridina tanks.    Hopefully this has given you some ideas.

      KH creeping up can only be from fertilisers that are added, or from rocks. As beneficial bacteria break down ammonia/nitrogen, the by product is slightly acidic water. This is a very simplified explanation. But the point is aquarium water will become acidic as the bacteria breakdown nitrogen. It is this acidic water that causes some rocks to increase KH or carbonates. What rocks do you have in the tank?
