I've had a canister filter since I set up my tank, so like 4 years now. I've used it to run carbon, etc. Well it crapped out on me today after running flawlessly all this time. I decided it was actually a blessing, to not have to unhook and clean the darn thing every week, so I pulled it off the tank. I plan on getting one of my hob filters out of the garage and just using that for media. Anyway, I just realized, duh - the other main thing I use it for is surface agitation. It's been 6 hrs or so since the canister quit and there's already a slight film on the water surface. I have an aqua c remora hob skimmer, so I think that is doing a good job of gaseous exchange. Is this a problem? What do yall do for surface agitation that don't run a canister? When I get the hob filter going will that be enough?
Thanks! I hope removing the canister on my measly 40 gal doesn't cause a cycle....
