HI my problem is i have had a little filter running in my main tank along side my main filter for the last 4 weeks. I was told it would be around 4 weeks for the little filter to become cycled so i put it in my QT and brought ammonia upto 5 ppm and left it running for 16 hours but the ammonia has not dropped so it is not cycled yet so how much longer shall i put it in main tank for ?
The bacteria in the other filter media will then move accross and colonise the sponge. The carbon only works for a few days after going in and is of no use after a few days. It is expencive to replace and just uses space that could be used for other things if left in, so I'd leave the sponge in it's compartment almost permenantly. That compartment in the filter can be left empty whan the QT tank is in use
