I have a 55 gal sw
aquarium with 50 lb live rock (30 more coming this month) and a 20 gal
sump. Exchange rate is about 400 gph
between sump and tank. I have a Yellow Tang, Percula clown, 2 firefish, 2 Yellow tailed damsels and a Blue/Gold Chromis. Also have 7 assorted snails and 5 assorted hermit crabs. All my fish are young and small, so I dont feel I am currently overstocked. I am using filter floss in my overflow box for mechanical filtration, a 30/60 power filter in the sump, and an Aqua-C Remora (also in the sump).
Now for the question. Can I eliminate the power filter in the sump? Id like to use it in a qt tank/refugium Im setting up, but Im unsure if I still need it in the sump. The floss is doing a good job of mechanical filtration (at least it gets dirty as heck) and the skimmer is producing well. Along with the filtration that the rock is providing, doesnt the power filter seem redundant?
All input is welcome.
