Tank, that drains through a drilled bottom

[dendro982]

Need to improve filtration of the debris from the bottom of 6g tank, fed very heavily (mechanical removal of uneaten particles of the dried Cyclop-eeze).
Tried 200 gph AC HOB power filter - debris are settling on the bottom after basting, instead of being picked by filter.

Toying with idea of drilling bottom of the 5-6g acrylic hexagon for draining through the bottom into the sump with micron filter sock, and adding the clean return water from the top.

Such system was mentioned here, but without any notions, what will prevent the water from draining out totally.

Any thoughts, links or other solutions?

DON'T DO IT!

Seriously.. a straight drain out of the bottom has no way at all of stopping if your return pump gets. clogged, burns out or just turns off. Your entire tank will drain and you will not be able to stop it.

how about a powerhead at the bottom of the tank to stir up the debris in a "cyclone" effect...

Just finished the search, it seems so too: others used closed loop - without filtration at all, or a canister filter, what is out of my plans.

No place for powerhead at the bottom of the NC6 with LR at all, in back chambers only.

As a temporary solution, will try bare 6g hexagon tank without LR, connected to the established 10g tank through it's 4g side sump with oversized skimmer and micron socks.

Suggestions are still welcome!
