Anyone with very large, or many tanks will probably not be interested in this, aside from curiosity maybe, as I doubt this is cheaper than buying RO water. I am writing this purely in case it may help someone else who wants an easy alternative to RO water.
I am housebound (have MS) and as such needed to find an easy alternative to RO water if I were to keep Taiwan bee shrimp successfully. I have red cherry shrimp in my 30L FISH tank (neon tetras, ember tetras, endler guppies) and they do well with virtually nil care (or attention since I mastered the TBs) other than dechlorinated tap water (which is needed for the fish anyway) so I won't go any further on that subject.
About 3-4 years ago I set up a 15L shrimp tank and tried BRITA filtered tap water, but had no real success with that and so 2 years ago closed the tank down and stored it away assuming then that that would be it, no Taiwan Bee shrimp ever....... but after 2 years of no success, at that point it was a bit of a relief anyway to just be done and out of the way. You will see from the Tap water readings below that in theory the Parameters were pretty good but from my experiences I think you need to go back to NIL (so either RO or the zerowater) and remineralise as I guess that way you know what the tests are picking up is only what the shrimp need - this is only my belief I don't really know, but ie the tap water TDS (Ph, Gh, Kh etc) was ok but what was in the Tap water to make the TDS reading what it was, if that makes sense? I have read on many sites of people trying tap water , as I did, with good parameters but it not working so that is my theory anyway! And of course domestic water supply parameters can change and if there has been any repairs in the system that will change it etc so from my experience only way to go is take it back to NIL and remineralise.......
A year ago (about a year after closing down the old shrimp tank) I came across a water filter jug from zerowater (www.zerowater.co.uk), an american product which I believe is available in Australia on Amazon, but may also be in shops out there for all I know). I thought, why not give that ago.... so I set up the old tank Oct 2017 (15L with the back part partitioned of for filter etc so probably 12L of useable aquarium) put some soil in and a few bits of Java fern and moss from the fish tank and ran it with the zerowater for a couple of months. I didn't ever get any Ammonia, Nitrite, or Nitrate reading but did see a bacteria bloom for a few days. I treated the zerowater as you would RO water, so added shrimp king mineral fluid gh+. There is a lot of info on the website about what it removes etc.
Tap water PH7, Gh 5-6, Kh 3-4, TDS 174
Zerowater Ph6, Gh 0-1, kh 0-1, TDS 000
I added 6 blue bolts about 6-8 weeks later, then some red ruby and red wine a few weeks later and 3 blue steel in March 2018. All went quite well, though there were a few deaths but that may have been me as I am NO expert, I do drip acclimatise though. April 2018 Eggs started appearing (difficult to see on TB) and by the end of that month shrimplets, woohoo!
Time for the new tank, dennerle 35L scapers which I got in May 2018 which I ran for a month with the zerowater, 2 cheap sponge only filters, heater, light, rock, wood, java fern, soil etc, and one sacrificial fish (don't worry he went in the fish tank afterwards as he survived). Then I transferred shrimps a dozen every other day(ish) etc. At this point I was obviously shutting down the small tank and although I had only bought a dozen shrimps originally, when I started removing stuff it turned out I had about 90 baby/juvenile shrimp in the tank, most were probably only days old (probably wasn't wise to transfer them at that stage really but I had too many anyway and wanted to get the old tank out of the way, as it was on the dining table). I THINK WE CAN SAFELY SAY THAT I HAVE CRACKED IT NOW, WITH THE HELP OF THE ZEROWATER FILTER JUG. So closed down the 15L end of June 2018. Daily now I see about 50 shrimps of half to full size in the new setup but haven't yet had any success with babies (though most of the shrimps may not yet be mature enough as I believe they need to be 6 months+), and with the hot spell (unusual for here when tank got to 30 degrees) and with me fine tuning the parameters, done now thankfully PH5.5-6, Gh 4.5, Kh 0-1, TDS 160 (something incidently I probably wouldn't have had to do if I had added the Gh+ from day 1 with the new tank). I will say that I NEVER had any Ammonia, Nitrate or Nitrite readings in the new tank either, but as with the small starter tank there were a couple of days of bacteria bloom. I expect babies will happen now I have stopped messing with the parameters, but there is always option B, set up the old small tank and use as a breeding tank, or C, buy more shrimps???? With the shock of how many babies there were hiding in the small tank, there could well be loads of babies in the new tank that are hiding anyway. I will give that a rethink if there haven't been any babies by xmas, though I have enough anyway at present. The only other things that may now affect babies (ie different than the smaller tank) is, the jets from the filters are a bit strong and circulate the water in the tank more, and I have rock (actually Geodes) in the tank???
I change 2L of water each week, mainly so I can squeeze the 2 sponges from the 2 filters and just clean the glass etc. I also use Fulvic acid, beta glucan and am just starting on bacter ae (hoping that may help babies). As with RO water, top up is pure zerowater and water change is zerowater with GH+ added.
Each zerowater filter does about 100L of my water (about 6-8 months worth) but there is info on the website above that shows how many it will do on different TDS basic water etc. The filters aren't cheap at £20 each (I have bought 4 for £50 so much more reasonable, and they don't have a shelf life anyway. They are of course available readily in USA in places like Walmart as it is an American product. If anyone knows where you can get them in other countries it may be a good idea to add it to this string/topic etc to help others, as mentioned before I THINK you can get them on amazon.com.au for Australia.
If anyone wants to ask any questions I will do my best to answer, but I am NO EXPERT by any measure.
Update 27 Sep 2018
I am daily seeing babies, in small numbers (all colour varieties), but from the top picture you can see there are a vast number of hiding places anyway, so there must be others. I have also seen a couple of shrimps heavy with eggs, grey, so they must be near birth...............
I will keep this updated if there is anything worth reporting, or there seems to be any problems with using the zerowater filter jug as a substitute for RO water but so far (1 year now) all has been very successful.
Update 7 Oct 2018
Probably be the last update - unless all goes wrong etc
I am seeing lots of babies of varying sizes and patterns now (20 today), so much so that I am going to have to start culling to make room for just the ones I really want to keep, and enough room/food etc for babies! I will try taking one big one out each week when I do maintenance and see how that goes!
Any questions just ask!
So the problem is, that my pH is always rising and settling in the range of around 6.8, but I fail to understand why and I hope you will clarify the problem for me. Let's get into details:
I am running inert substrate tanks, which have the following parameters: pH 6.7-6.8, GH 5-6, KH 0-1, TDS ~125.
My routine is that I do weekly water changes of around 20%. The water for changes is RO water + salty shrimp GH+ + Azoo Triple Black Water (which is basically a tannins and humic acids extract)+ Azoo Ph Lower, and I usually adjust the pH to around 6.0-6.2 as I want to keep it acidic, but the pH just won't go down lower than 6.7(to be exact - If I would add peat, or a lot of those acids, then sure it would go down lower, but after some time it always comes to it's usual 6.8 range). I also adjust the pH of the top-up water, which is RO + Triple Black Water.
As I am adding a lot of acids into the water I thought the pH should stay acidic, unless there is something that absorbs those acids.
So I did a test - I have prepared my usual bucket of water, re-mineralised it and adjusted pH to below 6.0 and let the bucket be. After around 24 hours I have measured the pH of the water in the bucket and, the pH was back at around 6.6. So it raised a lot. Once again I lowered the pH to below 6.0 using Triple Black Water only, and after another 48 hours the pH was again 6.8.
So why is the pH rising ? I understand that with kH 0 there is nothing to buffer the water, but since I am adding acids into the water and there is nothing that could absorb them what causes the pH to raise ?
Hi everyone, I have spent some time searching (unsuccessfully!) for any threads set up to address how to naturally and chemically treat the more important water parameters. Obviously I'm not talking about temp, but the PH, TDS, KH and GH levels are the ones I'm most interested in. Now I'm country based so the only water I've got access to is R/W and bore (perfectly drinkable from the pump itself, no brackishness) which I have used for 4 of my 6 tanks (tropical and a few lower grade cherries). But I want to better hone in the water condition as best I can so any tricks to raise lower the above parameters naturally or if need be chemically. Or if anyone knows/finds a link, anything will be appreciated.
Had put this in the pinned "Shrimps 101" but will try to delete it as it's probably better as a separate post.
Being rural makes water choice difficult and some of the values I've tested are way out, hence why I'm seeking advice.
Hey SKF peoples,
I'm just mixing up my RO water with a combination of GH+ and GH/KH+ to keep tiger shrimps in. And I thought I'd share my experience, I gradually added the minerals and measured pH along the way and I thought I'd share the results.
I note that the pH may change overnight after letting stand but I have been running a pump in the water to mix it well and aerate it so I doubt there will actually be any measurable shift.
As you can see by the results, the GH/KH+ pushed up the pH a LOT! Does anyone else have this experience? I have achieved my desired water parameters in terms of ppm and GH/KH however the pH is unreal.. and this is not the first time this has happened to me either. However t is the first time I have taken the effort to document the fact.
I'm planning on experimenting with adding a very shallow layer of the cal aqua labs black earth premium and monitoring the pH over the course of days.. expecting it to slowly drop...
Any input is 100% welcome!
love n peace
PS the initial drop in pH after adding the first lot of GH+ I understand can be explained (as I have read elsewhere) that when attempting to measure the pH of RO water using a pH meter the device can not accurately produce any result due to the lack of ions/conductivity in the water.

I'm hoping to get some advice and opinions on managing pH for a tank with cherries and bee shrimps.
My pH is measuring around 5.4 and I'm concerned it may continue to drop over time to unacceptable levels even for bee shrimps. Currently there is only CRS in the tank but I want to add some neos soon.
Firstly some background detail - I have a tank with a modest amount of cal aqua labs black earth premium as per the manufacturer's advice. I use RO/DI water (I changed cartridge recently and TDS of RO is zero) with SS GH+. I keep up with regular WC and the TDS is about 140ppm at last check. The tank is heavily planted, has quite a few pieces of driftwood here and there and also some catappa/IAL. There is oodles and oodles of filtration including canister and air driven sponges, and the stocking rate is low-medium. There is some benibachi fulvic grains in the canister (although these fulvic grains are roughly 6 months old and should be close to expiring now; however I will still remove these fulvic grains when I get around to doing some maintenance on the canister however). The shrimp are quite happy and new ones are regularly getting berried.
Anyway, so aside from removing the fulvic grains and possibly removing the indian almond leaf, and maybe some of the larger driftwood which may help to prevent the gradual acidification that is going on. I am wondering if anyone has experience using small amounts of aragonite or similar to help buffer the tanks. If anyone has any other suggestion or opinion it will be greatly appreciated. I don't fancy that cherry shrimps will breed very well in pH 5.4 or less and I really do want to keep some different coloured shrimps in this setup!
I will be most grateful for any input :-)
love n peace
-edit- I should add that it's true that as a last resort if it really comes to it then I could remove some of the substrate but I don't want to pollute the water in this way if I can avoid it..
