Is this normal??? Is it safe for humans to drink this? I thought I wasn't doing enough water changes, but then tested water right out of the tap, and was surprised to see 20ppm nitrates. 0 ammonia, 0 nitrites. Will my fish be ok? I do weekly 50% WC's. I also tested weekly on my 55g, usually 40ppm nitrates. My tank is about half stocked. Please advise.
