Help with canister filters

Hello all, a brief bit about me, I have a new 105 gallon tank, 210lbs of LR and 100lbs of LS, the tank has a 1.5" drain and 2 3/4" returns, I run the ASM G1X in the 20 gallon sump and a genx 6000 for a return pump. Now all is fine except the fine particals in the tank! I know I need to run a filter to polish this but am having trouble choosing one that is right for me and the job at hand. I have looked at several canister type but I have not been able to choose one for my tank set up. I need this filter to draw and return water to the sump. The question I have is, do canister type filters have thier own pick up pumps? I know that the FLUVAL line require a siphon to work, but I am not sure if all are the same, I do like the sounds of the new canister out from marineland, the c-360 and would buy it in a heart beat if I knew for sure I could stand it on the floor beside the sump and draw water from the sump for the filter...any help and or advice would be great. The DT and the sump are both acrylic so hanging anything from them is almost impossible.

Hmm, most, if not all canisters push water out of the filter, and allow gravity to feed water into it. If the water level in the sump is above the level of the pump in the canister, it might be OK.

Is there a particular reason you'd prefer a canister filter over something like a filter sock?

the sump is small and full! I was thinking of a filter sock on the drain from the DT but again being new I was not certain this would work for the fine particals floating around in the tank. Would it work if I matched a pump to the flow rating of the canister and just pumped the water to the filter and returned it to the sump? Having said that I am not sure I can swing another pickup tube in the sump...will have to look at that a little closer if it is something that may work for a canister.

I tried that when the pump on my canister on my old FW tank died. Didn't work, there's just too much water to push.

A 100 micron filter sock would pull out pretty fine particles, plus it's cheaper and easier to clean. They can still generate nitrates if not changed or cleaned regularly, but not nearly as bad as a canister.

ok I will look at that, will see what I can remodel to attatch a sock to the main drain and try that, thanks for the advice.
