Filter - (Fluval) Aqua-Clear 70.
Heater: Fluval 100 watt
Substrate: Have never used Floramax, but I do use Eco-Complete (same manufacturer). My African Dwarf Frogs have very fragile skin and I have had no problems with it at all. BUT, I mix a few handfuls of small river rock gravel in there also. I also have 3 cory cats that live in that tank that have absolutely no problem.
