 Re: Would this refugium/sump help?
Under gravel filters can work but they need a DSB to function well and they gravel must be vacuumed regularly to prevent clogging and dead spots. I used undergravel filters in SW 32 years ago and had no problems with nitrates running too high. But the best thing to do would be to get rid of your UGF. _________ 75g reef with Nova Extreme 8 bulb HO T-5 lighting, refuge, Remora skimmer, DSB, Seio powerheads, Acro's, LPS corals, assorted zoo's & mushrooms, Yellow Tang, Maroon Clown, Blue Cleaner Goby , Cleaner, Fire and Sexy Shrimp, Coco Worm, T.Crocea Clam, Derasa Clam
