I have a canister running on my 140l tank and was wondering is it worth trying to convert it into a mini dsb? Taking the baskets out and somehow reducing the flow because I think if I put a whole lot of sand in the canister it will just create a sand storm and blow out.

Any input will help. wanting to do this because I really don't wanna empty the tank and drill for an overflow or buy one of those rediculously overpriced hang on overflows.

gotta use this guy cause he's tempting me :slayer: OK it's outta my system now.

I honestly can't see it working, use the external to run carbon and or rowaphos.

That was my second option. Just didn't wanna waste the space as the canister is about ten litres I think. Which means that's a lotta carbon. What about an in tank DSB. Think I asked about it before but to lazy to go look back. Does it work? I think jaques is running one. Might be mistaken.

Ditto to Warr's answer.... And yes - I am indeed running an in-tank DSB..... Just wish I could more of the problematic live rock into my sump - but they've got corals growing on them :-( (the live rock is the cause of my nuisance algae issues - not my in-tank DSB)...
