I was struggling with bubble algae a bit. Nutrients kept bottoming out so I was dosing both NO3 and PO4. Cut out all the red, green and white lights. added two more PinCushin urchins to the two I had and added 10 Mexican Turbo snails. Big ones. They seem to love getting all over the rocks. Put my deep cleaning schedule to twice a week and cut my fish feeding quantity in half. Most of the algae is gone now and nitrates stay about 10 and phosphates stay at 0.04=with no dosing. I think the main problem was I was over feeding.anyone in here currently keeping acros successfully dosing nutrients and battling a bit with bubble algae if so @ me i got some questions.
