I have a extra mag-drive 18 pump that I am not using at the moment. I also have a oceanclear canister with a UV. Would it be possible to use the two to fulter my sump? I was thinking of using plastic flex tubing for the intake line from the sump to the canister, then out of the canister to the pump in the sump.
What I need to know if it will work with the pump being used to pull the water rather than pulling it.

Not seeing how big your sump is, I'd say, put the pump before the cannister and with the shortest hard plumbed intake from the sump. Properly primed it will draft from the sump but not through the cannister, too much resistance. Mag 18 is alot of pump so you might need to valve down the outlet, back into the sump to keep the sump return pump primed. Hope that helps, ~Z :thumbsup:

The reason i was thinking about putting the pump after the canister was because I thought it was bad for a pump to suck in crap.

I just took a "Shop-Vac" foam filter and sewed up a prefilter for my intake. Works mint and removes all the big solids. You shouldn't have too many big chunks of crap if you are pulling from the sump...!Z :thumbsup:

I have a foam prefilter on there already. Do you have a a pre-filter over the foam?

There is a slotted tube inside the foam sock I sewed...
1" PVC pipe with a 1" female thread to 1" slip adaptor for the pump end and a 1" cap on the other end.
Then I sawed a series of slots in the 1" pvc pipe to make a screen to back the foam you see...
