My reef tank has been cycled for 5 months now and all of a sudden i have an algae problem. The only thing i have changed in my system in the last couple of weeks is the addition of an InTank fuge backet, 10watt grow light & some chaeto. The issue i am having is this, it appears to be an algae/diatoms forming on my substrate, it only happens when the lights are one, once the lights go off, it goes away that evening and the comes back in the morning once the lights come on, is this normal for a tank that has been up and going?
Hardware: Innovative Marine Nuvo 8, 2 8 watt Skkye Light LED's. 5lbs of live rock, 10lbs of live sand, filter floss, cpe & purigen,
Livestock: 2 o clowns, lots of coral frags, trochus, nassarius, nerite & dwarf cereth cuc, rock flower & bta.
Chemestry: weekly 25% water changes using ro/di and ocean reef salt, sg 1.025, temp 81f, ph 7.7-8.0, no detectable ammonia, nitrites, copper, nitrates 2-5 ppm, phosphorous between 25-40 ppb (works out to .06-.1ppm of phosephate), alk 164, Ca 450-500, Mg 1280-1350.
My feeding of my two clowns is half a pipette of brine shrimp in the am, a pinch of marine flakes in the pm. No supplemental dosing of anything except a pinch of reef formula every second day for the two anemonies.
I have pics below when the lights come on, 1, 2, 4 6 hours. I also run my moonlights from 7am to 11:30pm, daytime from 8-8.
Is this a normal thing to happen to a tank after its been running this long? If yes how long will this continue? Is their something else i should be doing, checking since it does go away each night?
