I have had a 2 gallon tank for about 8 months now with RCS and plants in it. Marina i25 filter, 10W water heater 6 day water changes, fluval shrimp stratum. But in the end none of this has stabilized the water parameters Ph literally will drop2-3 points over nite and I wake up to dead RCS. So frustrating:wall:. I think just the small tank is the reason anyone have any suggestions on how to keep the parameters in check or even what other fish could go in there?
