I have a glass 135 and I originally designed the filtration for fish only. I would like to convert to a sump/refugium. What is a good brand overflow that can pass about 1000 gal/hr? I would like to put two of these on my tank which would give me about 15 turns an hour. The ones I saw at my lfs are only rated at 600 gal/hr.
