Fish Fanatic
Hi,
I have a 270 Litre Display tank with 60 Litre sump been running for 6 months now. I have an empty Orca 450 which I intend to use as a quarantine tank for some simple corals and a few fish on and off and as-and-when over the next few years.
I would like to keep some media in my sump to colonise with 'good' bacteria and then simply transfer it into the orca rear chambers when I have the need to set up the quarantine tank.
My sump has a filter sock and filter floss before the return section so i was wondering whether I could keep sponge blocks, filter pads or !!!!!Bio-balls!!!!! in the return section hoping they would be colonised without causing any Nitrate issues.
Advice on the best way forward and what would be the best media to use in the sump would be greatly appreciated.
Many thanks
