Ive been feeding my pleco those Hikari algae wafers, and he seems to be loving them. I have started to notice though, my nitrates have skyrocketed after use of these things, as most of the wafer just disintegrates into the water. About 10ppm to 40ppm in one day. Can i feed my buddy some lettuce, or can i get some suggestions on other things that wont make my water look like a porta-potty?
