So I tested my city's tap water today (out of the faucet)...the ammonia was about .5 - 1 (ARGH!!!!!) This really does explain a lot, I am pretty much doing water changes every other day in my tank because the ammonia builds up SO FAST, (50% changes on a 10 gallon) I need some brain power to come up with some ideas I only have 2 at the moment. 1-Use water from a filtering machine (less expensive but no trace minerals) 2-Bottled water(EXPENSIVE!!! but trace minerals) So If anyone has any input that would really help. If these are my only two choices i either need some options on good mineral supplements or mineral rich bottled water company (I live in Cali so anything that is localish or easily accessible here is a must) thanks for reading about me crying over my city's horrid water quality.
