I have been battling water problems for 2 weeks now. It seems that after the emergency tank change I had a spike in my ammonia and nitrites. Either way, I manage to get the water levels down a lot. My parameters right now are Nitrates = 0, Nitrites = 0.3, Ammonia = .25. my PH=7.9. I have been changing water for quite sometime and i just turned my skimmer back on. I have a purigen pouch in my sump and need to clean out my sump. The Colt looks all droopy and purplish. Any ideas why? It was doing fine when the water spikes occured and since putting the canopy on the tank it started acting up. BTW temp is @ 81.0
