Whats the current PH of your tank? Nerite snails quite sensitive to low PH. I had mine it's shell corroded and died after few months in the tank.

Advice from boss Felix


The PH has risen to 6.5! Shell is not corroded, but the meat is gone, probably eaten by the Yamatos.
Any idea what could have caused the PH to rise so much? I only added one more 2213 cannister with original substrate + anti ammonia rocks.
Will anti ammonia rocks have such effect?


leffhker, they are Dymax Anti Ammonia rocks, comes in a mesh bag. I added them into the 5 month old second hand 2213 from a forumer and together with the orginal ehiem media that came with it.
I am thinking that New Amazonia Soil is supposed to be lower in pH, so can't see what else would have caused the pH increase.


I discovered from the box that the Anti Ammonia rocks (zeolite) controls pH between 6.5 - 7.5! No wonder my pH shot up to 6.5.
Now i have to cause a mini flood to remove the zeolite from the canister!
