Hair algae!

I would recommend, as part of the solution, adding a tuxedo urchin. Mine is a work horse, the most effective of my cuc.

I’ve had a blue one for a few months. I love watching him. He had a crab stuck to him the other day

Not pictured that he has carried around: thermometer and a 6 inch leather frag. In the picture he is giving a ride to a rasta frag and a blue mushroom.

I have a similar situation. New to reefing. I have a 32 gal biocube. My DT is now 8 months old. At about 5 months started noticing GHA. At the same time nutrients had been trending upward despite being careful not to overfeed and I have always performed weekly 15% water changes. During the time the GHA appeared my nitrate went up to 8.1 and Phos 0.18. I have been manually removing but still present. I don’t think it has increased but I am just coming back from being away for a week so who knows. Before I left for vacation one week ago my nutrients on 8/19 were Itrste 0.8 and Phos 0.11.

- I assume that it’s due to the GHA absorbing the nutrients???

My goal is to manually remove/scrub.
I can remove some of the rock and scrub.

I have a few questions. Hope you can help.

I have read about using peroxide.
-Do I spray on the rock or wavemaker after I remove from the tank?
-How long to I leave it out of the water before rinsing (rinse with water from water change?)?

Urchins.
-I heard they are very good at cleaning GHA. Do they clean established GHA growth?
-I heard they can grab coral Frags that are not attached. Will they disturb those that are secured?
-some of my aqua scape is not glued down, just laying on each other. Could they disrupt that?

I have a CUC but they don’t seem to be making a dent in it. I do not want to use any chemicals and don’t mind putting in the work and understand that this is not a quick process. Anything else you can recommend?
