Canister Filters

Hello, Finally got my aquarium up and running with fish added on June 16.
I have an Aqueon Quietflow 400 canister filter for my 75 gallon tank.
So far so good... quiet and flow seems okay. I use the 2 "polisher hob" included for the return flow which use filter cartridges. Have changed a few times.

So.. the question is:

Generally, how often should I clean the canister filter? Rinse out the media with aquarium water, etc. Every 6 weeks or so??? Do not want to do it more than I have to!

Thanks,
Brad

My schedule.

Every 4 to 6 weeks.
Replace polishing pads.
Rinse sponges and media with tank water
Clean impeller and shaft.
General wipedown.

Every 12 to 18 months.
Replace O ring, impeller, impeller shaft and impeller cover.

The proper answer to your question is, "As infrequently as possible."

Why? Because no matter how delicately you clean you're removing biological filtration ability. This is particularly important when the filter media is new as it [seems] to take much longer to establish a bacterial colony on biological media like bio balls and ceramic cylinders than mechanical media like pads and hybrids like foam. You must maintain the permanent bacterial colony when cleaning.

In that vein the question really becomes, "How do I clean the filter?"

My suggestions are:

1) Get a 10-gallon galvanized wash tub.

2) Get a 1-gallon or so bucket.

3) Fill the wash tub about 2/3 full with tank water.

4) Remove the canister filter.

5) Unload the canister putting any permanent media like bio balls, ceramic cylinders and foam into the wash tub. Put any "filters" into the bucket.

6) Reload with new or cleaned "filters" doing nothing more to the permanent media than swishing a bit in the water in the wash tub.

Back to your original question of, "How often?" I suggest you wait at least 2-3 months for your new tank before the first cleaning.

Thank you... something told me best to leave alone until really necessary.
I am using the 2 HOB "Water Polishers" that was include with the Aqueon Quietflow canister filter instead of the typical return flow. The polishers use filter cartridges which in theory should cut down on the filter cleaning times.
I changed the cartridges a few times and the water is so clear the fish look suspended. In my 75 gallon I have 10 cardinals,5 tetras, 12 tiger barbs, 6 platys, 2 pearl gourmais,4 corys and 10 nertite snails plus giving all live plants a shot and everything doing great. ph 7.0 and NO ammonia,nitrites or nitrates

Best thing to do is buy a pre-filter and place that on the intake tube.

You donít want flow to slow down within the canister as the microbial colonies rely on a finite amount of oxygen based on the flow coming in. When that slows because things are getting clogged itís generally bad news so a great tip would be to monitor your out flow for signs of slowing.

A pre filter will allow you to collect gunk at the site of entry to the canister in theory preventing suspended solids entering the canister extending the cleaning interval. You can literally just remove the pre-filter. Clean and on put it back over the intake.
