Hi all. I'm at my whits end. I have a 30 gallon tank with 2 clown fish and plenty of soft corals. The corals are doing great, the fish are doing great. All the corals are extending fully and the nutrients are perfect. I've been doing frequent water changes, but I'm still overwhelmed with hair algae. I took the water into Aquadome and they said the water is fine. I bought two urchins and they haven't done much. I bought some emerald crabs and they died within a week of putting them in (maybe the starved?). I even performed a 3 day black out to try and get it taken care of. My lighting is as follows:
Fluval A3995 Sea Marine/Reef 2.0 LED, 48-60"
2 hour sunrise from 10 - 12
Daylight with pink 79%, cyan 100%, blue 100%, purple 85%, cold white 70%
2 hour sunset from 3 - 5
Someone please help. I've been fighting this for months.
