I have a 75 gallon planted tank that has been set up since August (upgraded from a 47 gal
) and moved in November. Got ick in December treated with rid-ick without issue and no deaths. Do monthly water changes usually about 20 gallons worth.
About a week ago i started losing fish. I lost all the of my danios, a couple corys, an otocinclus, a couple black tetras, two madagascar rainbows, and now another rainbow appears to be sick. Most fish show no indication of illness they will just be dead in the tank. A couple i have seen white patches like maybe there is something wrong with their slime coat. Started treating with rid-ick for 3 treatments then changed to melafix for currently 3 treatments. I have done a large water change and gravel vac. Nothing seems to be helping. I still have a couple black tetras and some of my large rainbows left as well as a pleco and 2 corys, a knight goby, and a clown loach.
Water has tested at normal levels with slight nitrates present. I've raised the temp to 79. I have changed my filters too. I am running two eheim canisters on it without carbon (ones a 60 ones a 30).
I'm at a loss as to what to do at this point. Any help would be appreciated!
