Embarrasingly dumb question about canister filter

823 Views 6 Replies 5 Participants Last post by  OverStocked
Hello - I have an Aquatop 400uv running for about 6 weeks now. It's time to clean it, and I really don't know how to turn off the water hose assembly to disassemble. I hate to guess and get water everywhere! I had an Eheim previously and it was pretty obvious how to do it with that. I think this is the same model as the SunSun 303b. Any advice is appreciated!

Got it - but does anyone have a manual?

... lost mine.
Flip the handle next to the hose connectors at the canister. Then, unplug the power. Pull out the bulkhead with the hoses connected, and place in a bucket. Remove canister, clean, put bulkhead back in place, push down firmly and flip handle back down. Then reprime and you are ready to go.
Thanks so much! I did just go for it and disconnected successfully! Thanks for the manual, too. Great help!
WOW, you clogged that thing up in 6 weeks? You may have some bigger issues than keeping track of the manual. You should be able to go for months at a minimum with that beast, if not longer. Also you should look into the proper way to clean it. Cleaning it too thoroughly can actually cause you to re-cycle your tank, causing other problems such as ammonia/nitrite buildups and deaths of your fauna.

Unplug FIRST. Then flip levers. If you flip lever then unplug you could end up with a mess....
