I bought a Juwel 450 about 12 months ago, and should have altered the stand to house a 3ft sump underneath, but didn't get around to doing it.
It currently has a large amount of live rock, a Canister filter, a fluidized sand filter, a rowaphos reactor, a TMC UV
, and a TMC v2 600 skimmer on it.
I'm now thinking now ways to add a sump, without emptying the tank.
I have an Octopuss overflow box and a large Eheim pump that I can use, the problem is the space in the cabinet.
I'm thinking of adding 2 18" tanks, using one as a refugium flowing into the other one set up as a sump.
Does this look okay?
Has anyone ever done anything similar?
