I unfortunately have some corals. They haven't encrusted to the rock yet so I MIGHT be able to pull them off. Only issues with that is I have no where to put them. I'm just going to keep doing water changes and watch nutrient import.You have hair and wire algae growing. Seeing no coral on this rock, I would place it in a container of tank water and pull off as much as you can by hand and scrub the rest with a firm toothbrush and some 3% hydrogen peroxide.
Return to tank, reduce white light intensity and number of hours of white lighting and add some snails such as :
Astrea
cerith
turbo grazer
trochus
A Pencil urchin
8-10 Caribbean blue leg hermits
Are you using RODI water or tap water from the faucet ?
What is your phosphate level?
Is tank at or near a window?
My tank is still incredibly young, about 3 months. I realize I pushed it getting the SPS into the system, but thankfully they're happy and growing. I just have the uglies going on.
I use RODI water.
Phophate was undetectable via Saliftert (tested 2 days ago).
Tank is near a window but heavily shaded and does not get direct and/or indirect sunlight.
CUC consists of 10 hermints (5 blue legs, 5 mexican scarlets), 10 ceriths, 3 nassarius (they're worthless), 10 trochus and 1 large white footed trochus (HE is new to the tank, but doing exactly what I got him for. Just doesn't move around much, which I guess is a good sign?
If I can't get a handle on it, I'll have to figure out something to do with my coral and get more aggressive.
