I have fancy gold fish in a small (around 30 gal) aquarium and I was provided with a Fluval 306 canister filter as a manufacturer's sample. While I realize this filter is probably overkill for my aquarium, I didn't have to pay for it and it seemed like a better filter than the old Powerfilter that hung on the back of the tank.
But I really don't have a clue as to how or when to clean it.
Do I need to continue to replace the carbon and how often?
What about the ceramic-type media? Does that last a long time or need to be replaced?
How do I clean it, with tap water, the aquarium water or?
Do I still need to do partial water changes? How much and how often?
Do I drain the water from the filter before cleaning it? How do I do that?
Any other thoughts or suggestions?
Thanks for your help!
hi i use a large canister filter i clean it once a month.
u got to use the tank water to clean the canister filter if u use tap water u will wash off all the good sutff off. what i do is put all the water from canister filter in to a large bucket then take all the media out the canister filter clean it all in the bucket of water from the canister filter then put all media back into the canister filter. fit all pipes bleed the canister filter job done
I have the Fluval 305, and clean it once a month. As wullmeister said, rinse the bio media in the old aquarium water only (the Fluval ceramic bio media should never need replacing).
Similar process to what wullmeister outlined: I pour the canister water out, take out the mechanical filter media and bio media and rinse them all in the bucket with the old tank water. Then I use tap water to rinse out the empty canister and get out any gunk. I replace the carbon bags at this time also (I'll be trying Purigen here shortly instead of carbon) and put the filter media back in. Snap back together and hook up, prime and turn on.
And yes, you still need to do partial water changes. I believe 10-20% once a week is typical for an established tank, depending of course on the level of nitrates.
Do you have to drain the water out of the canister before emptying it? How do you keep water from running all over the place? Maybe open it inside of a big bucket?
The canister has two "valves" attached to the hose end. Pull up the black valve all the way first to close off the hoses (and keeps water in the hose), then pull the grey one up to disconnect the hose end from the canister. There will be a little water that comes out so have a rag handy.
Pull out the canister and take to a sink. Undo the two side clamps and pull off the top (will take some elbow grease). There should be no spillage when the top comes off. You'll notice the canister is full of tank water. Remove the filter media and then the media baskets. Dump the water out of the canister and clean the inside with tap water.
Here's the videos on YouTube from Fluval on Setup (Part 1)
and Maintenance (Part 2)
These are for the x05 series but they should be similar enough to answer your questions.
That's helpful. Thanks!
