I've decided that I wanted to remove the cheap colored chain store gravel with eco-complete in my 20g tank, and had a few questions.
1) Is 20lbs of the new substrate enough for a 20g high? I know I wouldn't have enough for a 20g regular tank, but wasn't sure how much I should have for mine. I could keep some of the old stuff, if necessary.
2) What sort of potential issues might I have with ammonia spikes if I take the majority (or all) of the old gravel out and replace it?
