I recently set up a hospital tank for my betta, I put some filter media from my established tank in the filter to help with the cycle, it half work in that fact I have no ammonia, but I have been getting a nitrite reading. So I bought some API quick start and it has been a full 24 hours since using it and nitrite hasnt shown up yet, but im wondering how often should I dose the quick start as it doesnt say on the bottle, only when nitrite rises?
