6 year old reef tank with hair algae problems

I have 4 fish in a 46 gallon feed every day some frozen and do water changes with RODI every other week. Is there a product that can quickly reduce the nutrient levels?

 

Do you have a skimmer?

What are your nitrate and phosphate levels? Need to know levels when dealing with algae.

Are you running any GFO products?

 

Forgot, age of bulbs and lighting please.

 

I have a Aqua C Remore skimmer. I run Pura complete in a HOB power filter. I have no sump. Lighting is 2 150 MH 14 K Phoenix bulbs about 6 months old. RODI Filters brand new. I think I feed too much. I ahve a serpent star and a halloween hermit and only 2 other hermit crabs. Flame Hawk, Oscellaris CLown, Yellow Watchman, 6-Line Wrasse. I feel doing more water changes wont help. Is there any product that like sucks up excess nutrients. My Australian Brain coral is very happy at least. I have some hair algae growing on the underside of my huge Monti.

 

I have not tested lately Phosphates and nitrates. In the past with my API liquid test It would show 0 in both. I have 3 Koralia 1's and a Mp-40 on the side of tank I know on the other side of the tank with all the rick its kinda tight in there. Test read 0 for both nitrate and phosphate. Here are some pics.

 

I would cut back on the feedings for sure, your serpent will hate you for it.

If you can bulk up on your CUC with some turbo and asteria snails, that should help.

You can try some GFO or phosban or equiv.

And rinse your frozen food.

 

I use Pura Complete for my GFO.
