I just tested and right now my phosphates are at 0 and my nitrates are at 0, and yes I do have a protein skimmer. The tank is technically 4 years old, I moved it 2 months ago but managed to keep the sand bed intact during it. I have around 260 watts of light on there right now and the bulbs are fairly new(a few bulbs burnt out in the move though and have yet to replace them). My lighting schedule is from 7:40am to 8:30pm.
Your phosphate/Nitrate readings are off...it says 0 because the algae is feeding off of it.
If you don't have any inverts then
my guess is that food is getting into the rock crevices and feeding the algae.
You will have to clean everything manualy..get a bucket of saltwater so you don't kill your rock and scrub it. Use a turkey baster to try and clear the sand.
I have no clue how to run a saltwater tank without inverts. There has to be an eco system for everything to balance.
Sorry, but how to clean it up to start with is all the help I can offer, how to prevent it again later...
Why don't you want inverts?
