Hi all,
Ok this is probably a repeated question but here is goes. How the heck can I reduce my algae.

Nitrates: <20 ppm
Nitrites: 0
Phosphates: 0

I am running 42W of UV. The water I add for evaporation was only 5 ppm...now with my RO/2DI it is 0 ppm.

There is no sunlight hitting the tank. I am not overfeeding. One cube of food a day for 9 fishes.

I am running a protein skimmer. The pictures below do not look as bad as it actually is. I will scrape the algae off the rocks but 1 week later it is back. Within an additional week it is worse than this.

I do not think the natural filtering is happening when I have this much algae covering all my rocks and floor. Some of the algae is red. I do not care about it. I can remove it with algae cleaner. It will be gone in 2 days. But I cannot get a handle on the damn green algae.

Algae

What can I do?

Thanks,
Zak
P.S. I have my lighting on timers. 8 hours full, 1 hour before and after with actinic for sunset. At night 8 blue LEDs.
