Yeah.....that small tank and that stupid undergravel filter. Do you
recommend the Aqua Clear hang on the back filter? I keep adding AmmoLock
to the water every other night, cause the ammo levels are scary. Gosh,
changing 90% of water, you think would at least help a BIT. Yeah, I do
see some buried crap under that stupid filter. Should I maybe not use
ANY gravel?

Why is the water finally so clear, if the ammonia is so high?
