water changes

Postby cosmiccow » Mon Oct 15, 2007 8:03 am

I noticed something yesterday after I performed my weekly water change. I tested for ammonia after the water change (50%) and it showed a small amount of ammonia. I changed the water in all four of my tanks and they all showed ammonia. By this morning the tanks measure zero ammonia.
Is this a natural occurance? Everything is healthy and looking great. No stress to the fish either. I wonder if it is a false reading?
Any thoughts?

have you tested your tap water yet?

might have some ammonia in it? if so keep the water changes down to about 25% unless its heavy stocked or a planted tank using high dosings of ferts :D

Turned to Nitrate? I was testing water at work, and a few had no ammonia, but terrible amounts of nitrate and nitrite.

A bunch of the ones in the store were randomly like that, and one lady whose water she'd brought in was like that too. She'd added two fish on monday, and wanted another. Very little ammonia, but the nitrate and nitrite were off the charts. Surpised the fish were still alive. Recomended a half tank water change. It was that bad...
