I added an AquaClear HOB
filter to my 26 Gal
tank. It had been running with only a HOB
Skimmer. I have 35lbs of live rock and about 2 inches of sand. I added the filter because I was looking for a place to run different types of media like carbon and such. I know I need to keep the filter clean or it can add Nitrates. I already have a bit of a problem with nitrates. I can never seem to get them below 30. I do weekly 25% water changes with LFS
pre made RO
salt, and I use their RO
fresh water for top offs. I have checked their water for excess Nitrates, and Phosphates, all their levels look good. I have a clown, a royal gramma, firefish, and cleaner shrip in the tank. I feed once a day. I have added quite a few nice corals to my tank and they all look good, but I really want to drive my Nitrates down to below 10 if possible.
