Best mechanical filter?

[Matt LeBaron]

Was doing some tank maintenance today and I was blowing a bit of my rock off and noticed a bunch of gunk/dust/whatever fly out of a couple of places. I have some minor algae growth right now and I'm wondering if it is because of a bit of build up on my rock. My tank is low flow in much of it (near the bottom) because of keeping seahorses so I was thinking about buying some type of canister filter, really stirring things up and hooking the canister filter up to the tank to assist in getting all of the stuff out rather than just letting it resettle.

 

I have a couple of Rena Canister filters that I kept after I went to the salt side from freshwater years ago but even filling them up with filter pads I'm not super confident that they would do a great job in removing this very fine sediment. And because of that I figured I'm post this asking if anyone had a better suggestion for how to go about this?

 

Thanks,

Could you have the output go through a filter sock or fine media bag?

I have a filter sock in my sump where my DT and frag tank empty into but judging by the fact that I have to clean the bottom of my sump every so often I don't think it's really catching everything.
