When I first started my tank, I was told that the bio filter was a good thing because it converted ammonia (bad) to nitrate (also bad) and then to nitrite (good???). I've been told that even nitrite is bad if the level is too high. I now have more testing supplies (for all three) and additives to bring levels down. What's the real story behind all this? Is there a better way to control these elements?
