Well, the other day I had a revelation with DAVENZ. We were talking of trites and trates, and I mentioned that my trates were climbing, cuz I have a can filter right now (not for long) today sometime will enact SUMP. I yanked the innards out of that baby, and my nitrates fell by 50PPM overnight, less than 24 hours. Ammonia is still 0 and nitrites are 0. question is.... damsels this morn wont eat, and the Fiji blue damsel is MIA. They are definately lethargic, and my question to you folks is.... Does any water parameter change stress these little guys out... even if its going to the good side of things ?
