so... and I don't want to hijack this thread either... placing a fuge in line with a DSB section isn't the answer, right? The split feed for both should result in greater flow into the DSB with a minimal flow into the fuge with algae, correct?

Aside from pod production doesn't the macro lessen the chemical levels in the system? And as far as a SSB for the macro, I assume something no more than an inch? Six for the DSB?
