Brown algae problem

[reefbumgm333]

I will second the phosphate reactor. It helped me when I had a huge problem with hair algae. After taking it off and using the reactor with carbon while treating redbugs, I did not run the phosphate reactor for a couple of months and started getting hair algae again.

Here is an update. I did a three day black out hoping this would help the problem.
After the big unveiling, all of the brown algae was gone. As to not shock the system, I slowly acclimated the light (nightlights only first, then Actinics only, to 4 hours full light, and now full 8 hours of light). I have changed my water change schedule and have had success for the last two and a half weeks.

The corals are doing great, the torch corals, frogspawn, and candy have ballooned back to their normal size and are about to split. The SPS corals are still doing great, except for the Monti. While I had the brown Algae issue, the Monti seemed to be doing great. The polyps were extended and it looked really good. However now that the brown algae is gone, the polyps seemed to have retracted and hardly ever extend. The water parameters are good. No measurable amounts of ammonia, nitrites, or nitrates; still at .5 phosphates; and Calcium and Alk are where they are supposed to be. Any thoughts on why the Monti has not yet come around?

Awsome news...though i am late to seeing it.

I hardly see my monti have polyps out...sometimes they are out...usually not. As long as color remains and you see growth on the edges...don't worry. Only if you see color fading or necrosis is when you worry.
