Aquaclear 150/ need advise? I have a question! I have a Aquaclear 150 HOB filter that I used on a fresh water tank. Its now just lying around. Could I make good use of it on my 120L reef im building up? I have read up on HOB refugiums, algae scrubbers and phosphate removers. Now im wondering what would be most beneficial to my tank? Any other suggestions for a good use would be most appreciated. My tank specs on Newbie thread link below. Newbie! - Marine Aquariums South Africa Thanks!!
