Thin green algae on rocks

Would a couple of pin cushion urchins help with this type of green algae? 160 gallon tank
TIA!

A Pin Cushion urchin will help. I would be a little hesitant to add more than one unless you plan on removing it once the algae had been cleared up to avoid possible starvation. How large is your tank? Urchins will also consume coraline algae so that may be a consideration for you.

I see you have a snail and hermit crab in the picture. More of these can be added as well.

How old is your system and where are you keeping your nutrient parameters?

Hey there, the urchin will and of course consume the Coraline algae. If you want Coraline algae, maybe there are other options.

Tank is going on 2 years at the end of March. N03 is 5-10ppm, p04 right around .1ppm. It is a Red Sea reefer 750 xxl so the display is 160 gallons
