So, my Fluval filter (in the QT
, which still has water in although the filter/heater isn't on) has 2 foam pads in it - one which I colonised with bacteria in the main tank for 2 weeks before putting it in the QT
Question is, will there be still enough bacteria on the 2 pads in the QT
if I do a 100% waterchange and put main tank water in the QT
(I need to take all the water out of course because of the high Nitrites). The tank is still full of water, but the filter hasn't been running for 2 days. It'll also take me another 2 days to do the new water (to replace the water taken out of the main tank). So that'll be 4 days without the filter on in the QT
Or, would you start again and take one of the pads out and seed it in the main tank for 2 weeks, and let the 2nd pad dry out?
