hair algea taking over refugium

[Smokeshow]

I have a 75g dt and a 55g sump. Tank has been set up for a little over 2 months. Just before the one month mark I put a softball size piece of chaeto in the refugium. Last week I took some out that filled 1/2 of a 5g bucket. I have a 2" sand bed and a large rock. The refugium is fed from the return pump. The pipe and sand is covered in ha. The dt is clean besides a bit of algea on the glass and rocks. Im guessing its from the cuc which is 3 blue leg hermits, 3 turbo snails, 2 other snails(can't remember the name) and a cleaner shrimp. Also have a lawnmower blenny and flame angle. Would adding some hermits or something to the refugium help keep the unwanted algea down? Nitrates are about 1ppm and phosphate is barely detectable.

I would try and get your P04 more detectable before you awaken anything else. I also have hair algae in my refugium that I just manually remove. I’d rather have it in the sump than in the DT. I would add more snail to help with the hair and film algae. Hermits are a hit or miss I believe. So I’d go with snails instead of hermits.

I removed most of the chaeto leaving a softball size piece, reduced the refugium lights to 6hrs a day and haven't run my skimmer for the past 4 days. Feed the fish 2-3x a day. Feed flakes, sinking pallets and frozen foods.
