Thanks for the replies. The water use to stink bad before I added the marineland, now there's a small amount of odor. SO, if u were me you wouldnt try another water source. The problem is just with my fish? BUt with any tank that is established, ammonia shouldnt be an issue unless the tank is way overstocked. And i dont think my mine is, I asked my manager who has dealt with fish for the past 20 years and he said these fish would be fine in the 46g for now. Im just not sure if my ammonia is high considering the tank has only been up and running for a month and a half or becasue I kept cleaning the gravel each week, which sucks up the good bacteria, this is what I have read.
