Well, I made a really stupid mistake. :sick: I was switching the filters on my 27G from an AC150 to an Ecco 2231 completely forgot about the lack of bacteria in my 2231. I meant to put the sponge from the AC into the canister to help seed the new filter, but in my excitement forgot. Darn!!
To cut to the chase, my tank had a huge spike in nitrites (no ammonia present). I've done a major water change on the 25th. Unfortunately, my silver dollars seem to have been labouring a bit under these conditions, i.e., opening/closing mouth, appear to be breathing heavily. One of them looks a little weak.
Would adding "Cycle" help the situation? If you have any other suggestions then fire away.
Cheers!
