Ammonia? Nitrite? Nitrate? pH? Is the temp actually 72? Any tankmates?
I would try Pimafix. I would keep the filter running and remove the carbon. Turning the filter off is just going to cause more problems, stress them, and keep them sick or make things worse.
ammonia: 5 ph: 8.4 nitrite:0 nitrate:0 alkalinity:300 Hardness:300 Chlorine and chloramine: 0 i dont have Pimafix neer my pet store no tank made i did remove the carbon out of the filter it 72f in the tank i still use maracyn
