I’ve had 0 nutrients in my 40 breeder for a long time because I only have 3 small fish in the system, after my corals have started losing colors I started heavier feedings and got my nitrate up to 2.5 and phosphate to .25 and the colors look better than ever but I’m starting to get a lot of algae. Does anyone know why I have a lot of algae with 2.5 nitrates and some people run 20+ nitrate with no algae?? I’m assuming it’s some type of gha. I have increased my cuc and they don’t seem to be taking care of anything except for the glass.
