Canister Filters, do they provide enough O2 saturation
Hello, I was an avid fish and Aquarium enthusist when I was younger, I havent had a tank for about 10 years now, I was in school and moving a lot so I couldnt give the time, I am ready to get back into fish collecting but wel...........l things have changed. I see a lot of these canister filters, I only owned one before and it was for a 600 Gallon Tank. My question is do these filters provide enough oxygen saturation levels that an air pump is no longer neccesary? I seem to be getting that impression as I am looking into newer set ups. Also found that when using a canister filter under rock filters are exempt as well? If anyone could give me some info on this that would be great, Thanks
Welcome to Fishforum.com.:wave:
If the canister filters create plenty of surface turbulence, you will not need the airpumps. Airpumps can be redundant if you already have a lot of surface agitation responsible for the gas exchange by lifting off the dissolved carbon dioxide.
For power crisis and other emergencies, it will not hurt to invest towards battery-operated airpumps instead.
What Lupin said.
Also the undergravel filter is not necessary if you have a canister.
Aim the return of the filter up towards the surface so it churns things up. That'll give you plenty of agitation and your best O2 transfer.
Hey Lupin, foregive me this may not be the best place to ask this but, what you had said made me wonder what i would do if i lose power... of course use a battery powered air pump. but past that if the power was off for an extened amount of time say 3 maybe 4 days...what would you do? feed less, a water change or two?
Get spare batteries to continue filtration/aeration especially when you have a corner box filterto stuff the established filter media in. Aside from that, do feed less and do daily water changes assuming you don't use the power to source your water. A generator isn't a bad investment either.
Unless you have some fish that require it you can simply stop feeding all together for several days with no ill effects.
