^ That. The reason I am asking is because I have had to treat my ranchu QT for septicemia. Unfortunately, the kanamycin is just wreaking havoc on the biofilter but I had to do it. I have plans to buy cycled sponge filters once if they make it through this but, in the mean time, ammonia is climbing fast in the 20g where there are two fish. I'm having an easier time managing the ammonia in the 10g with just Sayuri but it's still there. In the 20g, ammonia is already at .5ppm and I cannot do anything except add Prime until tomorrow when I do a 50% WC prior to adding the second dose of medication to their tank. I figured since my cycle is already a mess, I might as well try an ammonia remover. So I picked up the AquaClear Ammonia Remover. However, I'm thinking it's probably just zeolite, right? If that's the case, I can't use it as the tanks have been salinated for the infection. Right? Maybe someone can help me understand a little better the interaction between zeolite and salt? Is there any way around it? If I did/could/should use it, it won't reduce the efficacy of the medication, will it? I have a little more faith in Prime's ability to detox ammonia rather than nitrite and I tend to think nitrite is the real monster in cycling BUT I do not want to compound the progress they have made so far with ammonia, and I'm concerned about the rate of increase. Can anyone help? I plan to call the manufacturer tomorrow to ask these questions, they are closed now, but I'm hoping someone here can help me out.
