PH Level for Crystal Red Shrimps

Recently encountered problem such as PH Level in tank keep lowering (from PH 6.2 to 5.6) despite changing of 1/4 of water and put PH up solution. After changing of water, the PH level back to 6.4. After a few days, it will decrease and decrease till 5.7. So far saw 4 casualties crystal red while other shrimps and fish all remained okay.

What could be the cause and how to maintain stability of PH level? Suspect is the media in the cannister. Black carbon with rocks, Biohome, ceremic rings and wools.

what soil are you using?

Soil is ADA II plus some magic soil

If it is newly setup your tank is not ready for any shrimps. Need change more water few times until pH stable around 6.8 before introducing shrimps, meanwhile suggest place some coral chip into the canister once pH starts go up then gradually take out small portion bit-by-bit and monitor closely.

hey bro!
i also encounter similar case...
my new tank is also like that
but my ph is 7.6 plus
so i add PH low solution..it goes down to 6.6
but after 1 hour or more, i increase back to 7.6..
i am using magic soil.

Ok Thank. Will do so but can i hang the coral chips inside the tank instead of putting it in the cannister? If I do water change, must i everytime add the Sachem water conditioner or just simply tap water?

I tested a few conditioners finally use Seachem Prime until today, reason: it will not raise up TDS. New CC effect is pretty fast, either inside cannister or inside tank will show u result in days but old cc is quite slow (my preference), buffer increases gradually, so we shall have sufficient time to do correction whenever necessary.

When doing water change, I pass tap water slowly thru carbon block water filters into a small container about 10L; then add few drops Prime and stir up for a minute and I can smell chlorine sometimes. Tap water pH shall around 7.2 and TDS about 55 in my area, I don't adjust pH because I know that the water is very soft. My only concern is diff of temperature (6C) when add into the tank, slowly cup by cup adding takes 5 mins for 10L water.

Don't use pH down... As far as I know it is diluted sulphuric acid either in power or liquid form. Even Seachem Acid Buffer powder also caused me big lost
