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.

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.

Cold or hot water not working 

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

Calcium carbonate is lime right?

Yes, or limestone.

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.

      Welcome fellow UK shrimp keeper! I would think it would be better to remove the shrimp into the quarantine tank and keep them there whilst you treat the fish in the main tank and once you finish treating the tank and fish do a complete water change (maybe 2 a week apart for safety) before returning the shrimps. That would seem the best option though obviously the shrimp would need to be in the separate tank for weeks. I'm not aware of any medications available for ICH that won't kill shriimp and/or snails. With neocaridina they probably will just about survive 30 degrees but you are pushing it close to the limit! I don't believe ich affects shrimps.

      Re-posting here from The Shrimp Spot forum as I need help. Help, 40 litre tank has a ich (ichthyophtyirius multifiliis) / white spot outbreak. We've been able to separate the few surviving neon tetra into an emergency quarantine tank, with appropriate medicine for the fish. We had done this as we had noticed the issue practically too late as we miss identified the white spots as cotton mouth (which the tetra also have). We luckily quarantined the fish from the tank as  the ich reached its second stage as most have matured and abandoned the fish. This has become an issue as even if the neon tetra do not survive the treatment, I cannot re-add them to the tank and I don't want to keep the tank's environment full of parasites. Thankfully ich seem to not be able to effect the shrimp but the medicine we have for them is toxic to the shrimp and the plants in the tank, hence the separating of the neon tetra. I was wondering if there was anything I can do to the tank while the shrimp are still in the tank, as removing them isn't a viable option. We've been trying to get the temp of the tank to 30C and leaving it at that temp for an hour, however the tank's heater is verry slow and doesn't seem to be going up past 27C. From what I've searched 30C should kill of the ich without irritating the bloody mary shrimp too much (too many websites vary their recommended temp, so I wouldn't keep it above 28C long if we were able to get it that high) If anyone knows if there are any ich treatments or methods of killing ich that are safe for invertebrates and potentially plants I would love if they could suggest one.

      For beginners and smaller tanks, I recommend glass aquariums because of their affordability and scratch resistance. For larger, more advanced aquariums, we recommend acrylic because it's lighter and easier to repair than glass.

      Hooray! I was hoping it was molt but he hasnt progressed at all in about a week. Thank you guys so much for your help again. Ill keep an eye out.

      It looks like the shrimp is about to moult.  I don't keep Ghost shrimp, so I'm not too familiar with how they look when going into a moult. But the white band along each joint is common in other shrimp when they start to moult.
