RO SYSTEM

Hi what pre filter and post filter do you use in RO SYSTEM?

Thanks

 

All RO systems should have a minimum of a Carbon prefilter, then the RO membrane, and finally the Resin post filter. And it should always be in that same order. Each filter has a specific role.

Are you planning on building one yourself? Or are you buying one from a shop?

I already order the ro system, later my package will arrive 

It includes the t33 carbon post filter

Im thinking to buy additional resin to lessen the tds of my water.

My question sensei is 

Are all resin filter can be use in shrimp? Either the t33 carbon? 

My pre filter is 

1. 1micron sediment filter 20"

2. Granulated carbon 20"

3. Carbon black 20"

4.1micron sediment filter 20"

5. Ro membrane

6. Either t33 carbon post filter or resin post filter

 

My goal is to achieve 0 tds or lesser  than 10 tds

Yes, resin filters and Carbon filters in RO systems can be used in all shrimp tanks.

You just remineralise the water differently for different shrimp. 

Does your RO filter have 6 stages of filtration?!! That's overkill, but it will certainly give you 0 TDS with so many filter stages.

Are you sure you got Calcium Sulphate?

Is it in powder form? or is it larger like pebbles?

Show me what Calcium Sulphate you got.

Its in fine powder form

It should dissolve in water. Use cold water. There might be some residue left over in the container. Just leave it there. 

Give it a good shake before every use.

It can't hurt to try it in hot water. Try it in a tightly sealed container so you can really vigorously shake it for couple of minutes, let it cool and  shake it vigorously again?

It can't hurt to try with some hot water from a kettle, it may help and you then just let it cool. You may need to keep shaking it vidorously every few minutes as it cools also!

I haven't actually had to disolve Calcium, but I have heard it is a difficult thing to achieve from other posts on here I have come across!

I don't see it as making any difference, but I am no chemist. Worth a try to just see if it actually dissolves better first and then go from there, it may not make any difference and still not dissolve in which case you will know there is no point using hot water and we need to keep looking for a better solution?

Calcium Sulphate dissolves better in colder water. It's worse in hot water.

I don't think you have the right Calcium Sulphate.

Not all Calcium Sulphate is the same. There is Dihydrate (Ca2SO4 +2H2O) and Anhydrite (Ca2SO4) Calcium Sulphate. The addition of the 2 naturally occurring water molecules in Calcium Sulphate Dihydrate make this type of Calcium Sulphate more water soluble, and therefore, it will work that much faster when applied.

Not all calcium is soluble.  Calcium Carbonate – Limestone -, for example, is not soluble.

Make sure you have Calcium Sulphate Dihydrate. 

Calcium Sulphate Dihydrate can be known as Gypsum by it's common name.

Can you send pic whats lookw like the

Calcium sulphate magnesium sulphate

potassium sulphate 

and trace elements?

So that i know the difference

thanks

Sensei is the magnesium sulphate is epsom salt? And its look like crystalized?

Yes, Magnesium sulphate is commonly known as Epsom Salt.

And yes it looks crystallised, like sugar. 

Calcium sulphate Dihydrate and Potassium sulphate, both just look like white powder. 

You won't be able to tell the difference in calcium sulphate just by the looks.

Pictures here, if you want a look ... https://www.kegking.com.au/beer-brewing-ingredients/adjuncts.html?p=2

I have mixed the neo minerals

Its different from calcium sulfate

And the residues of lime is lesser than the calcium sulfate but the residues that remains in lime is like a sand

That sounds right. Limestone or calcium carbonate has carbonates which do not dissolve in water. Those sand particles are most likely the carbonates. If they get in the tank it will dissolve very slowly, but no harm done.

      Update to say that after a few gravel vacs, front wall scrub, moss / floating plant trim, that the condition seems to have improved.  My current theory is that it is due to waste / debris management, where "stuff" like that brown mulm accumulates in the substrate and behind the HMF filters.  Maybe some tanks can somehow deal with it, but mine can't.  Also another experienced shrimper suggested that maybe those "shell bugs" don't just live on the shrimps but also in this debris.  Maybe this is the reason some tanks fail due to "old tank syndrome" where all they need is a good gravel vac? Also, I am guessing that plant trim helps too because now more of the nutrients and light go into growing algae instead of more plants? Well anyway for this tank I will try weekly water change and monthly gravel vac / plant trim.  For my next tank, I'm thinking of something like an under-gravel system where this mulm can fall down and I vac it out.

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony.

      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!
