I have a 60 gallon tank with 4 110 watt VHO lights on it. Tank is 1.5 years old, and I am battling green hair algae with a vengence.
Lights: 2 110W 50/50 actinic white, 2 110W Actinic blue URI
Am I running too much actinic lighting? Too little? Lights are on 8 hours a day.
I am wondering if my lights are somewhat responisble for the algae. I use RO water for top off and saltwater, change 10% water monthly, and feed as minimally as I can (pellets eaten within 30 seconds). My trigger recently took out two shrimp due to the feeding cutbacks, who got along for 6 monthspreviously.
Fish and Cleaner Crew:
12 Emerald Crabs
6-10 hermit crabs
1 6" long Bali Sea Monster (does not eat the hair)
4" Foxface (does not eat the hair)
3" False Percula
3" Niger Trigger
4" Pygmy Angel
2x 3" Yellow Chromis
5" Bar Goby
2 bubble tip anemones
Fair amount of leather coral, SPS, pulsing xenia, and other soft corals.
1/10hp chiller (77/78)
Euro Reef skimmer
300gph turn over from sump to tank (via chiller)
I add kalkwasser, calcium, and alkalinity supplements etc.
Water parameters:
pH = 8.2
Calcium = 450
Alkalinity = 11.9
Phosphate = 0
Nitrate = <10
Nitrite = 0
Ammonia = 0
Salinity = 1.025
