We did some upgrades to our lightning system changed to a 6 lamp T5 nova pro fixture from a hagen 2 lamp T5 system. In addition we added CPR HOB refugium and top off system. Corals are looking great under new lights. Colors are great. Seeing lots of new growth in corals. Salinity has been rock solid. I think that is due mostly to the top off system.
However can't seem to get the nitrates and phosphates under control. That is why we added the refugium. We still have from time to time diatom, brown algae, green hairy algae and red cyano blooms. Right now in the middle of an algae bloom.
For the past 3 weeks have been doing 10% water changes every 3 to 4 days, physically removing the algae from the walls and rocks, siphoning, up the changing of the filter material which is full of black brown material and reducing the photo period to 5-6 hrs. Going to try another 2 or 3 day period of no lights at all. We have ordered a clean up crew package online to see if we can get ahead of this. In my research it seems that we were a little light on total number of snails, crabs, etc. in our tank.
One positive thing during this period is our apatasia problem is vastly under control. The amazing thing is corals seem to be doing well except for our bubble coral that we added. I have moved that one to another tank to see if we can get back on track.
Any other suggestions that we can try? We have added carbon, GFO?
