couldnt think of anything more..but i think DSB would be a bad idea

[weileong]

how come DSB bad idea? I thought the primary function of the refugium is for reducing the NO3 and PO4 as well as the cultivate those pods etc?

DSB needs at least a footprint size of a standard 50g tank to be effective..and be placed in the display tank where the waste will be accilimated.

swallow sandbed / few pieces of LR r good enu for the pods to reproduce...

The macroalgae will help in the reducing NO3/PO4 ..

try to get some ulva..they're used by farmers to cultivate pods .. heard it grows well in PO4 rich(not sure how rich) enviroment
