I have been working on my 150 gallon lately. It has a sump that is ~40 gallons.
Some of the things I've been wondering about are:
Making a refugium in the middle compartment. Has anyone used the refugium mud? is it worth it? the middle section in only about 15 gallons. Is that even big enough to make a difference?
Do you guys use filter socks? I'm debating redoing the plumbing into my sump and adding a filter sock. would that be worth it? if you guys use them, how often do you change them out? do you just rinse them in the sink and reuse them?
How much flow do you guys have going through your sump? low flow or hi flow, and why?
thanks for the info!
