Moving from sponge filter to canister

Hi guys. I recently bought an 80 gallon malawi cichlid tank, with fish. It seems to be a healthy tank up to know - the previous owner was very experienced, but also doing everything on the cheap, which is admirable. However I'm going to swap out the sponge filter is has now for a canister (fluval FX5). I just wondered - what's peoples opinions of the best way to switch these over. I don't really want to run them at the same time - too much flow

I was thinking:
a) set up the canister, with its media baskets (eheim mech pro, eheim biomech, eheim substrat pro), then wring out the sponge into the new filter onto the bio media, squeezing as much mulm in there as I can. Top up with tank water
b) chop up the sponge and put it in with the bio media
c) rig up the new filter, but leave the old sponge floating in the tank for a week

a) is probably my favourite at the moment. What do you guys think? Any more suggestions?

I vote for option C and would wait for a couple weeks before removing the sponge or adding anymore fish.
Option B would prolly work as well, but I would still resist adding anymore fish for at least two weeks.

As others have said B or C will work. Sponge filters do not create much flow so I would not worry about there being too much flow in the tank. If you are using the orginal gravel and it was kept wet than a lot of the bacteria will already be established in the substrate also.

Thanks guys. Yes, the sand was kep wet and it's the original sand. I have to say for C), I was just thinking of turning off the sponge and leaving it in there.

I've just had another idea - How about I take the pump and the tube out of the sponge, then put the sponge over the inlet of the new canister? The incoming water would flow through the sponge first, acting as a kind of prefilter, and hopefully transferring the bacteria in the sponge directly to the canister. If I leave it like that for a couple of weeks, then take off the sponge and just replace it with the FX5 inlet sock, what do you think then?

That would work too.


Hopefully it won't restrict it too much.

To be honest, as itis only a 80g tank, and the fx5 is rated at 925gph, I was thinking I would need to dial it down anyway. I don't want the fish to be fighting a monsoon constantly

You never know, most fish love a current. Not sure on your particular fish...
