I have the 2 flanking actinics on for 12 hours and the other 4 middle lights (one actinic and 3 white T5's - cannot remember the name) are on for 10 hours.
They were all bought brand new with the tank. I get a smidgen of natural light, but nothing direct for for a long period of time. Nitrates are at zero...and I have not run other tests recently, but was planning on doing that the next few days. The skimmer seems to collect alot of green skimmate (guess that is normal) and I clean it and the sock every few days. I have no fish yet - just snails and a shrimp. Had 10 hermit crabs I bought 3 weeks ago, but do not see any anymore - tho lots of places in the LR to hide

Read the guide in my signature about nuisance algaes, and if you have any questions after that I'm happy answer them. As per the guide, hair cutting and turkey basting make a huge difference. The guide also explains why your tests are coming out ok, but the algae still persists. They are false 0s. Also, your middle lights (usually referred to as daylights) can be run anything from 6-12 hours, so you can play around with a shorter photoperiod and see if that helps, but hair algae relies very little on light.
How are you cleaning your filter sock? How many snails did you buy, and what type? Side note...the specifc gravity in a reef should be 1.025-6 which simulates average natural reef SG. Last edited by Myka; 04-21-2009 at 08:05 PM.

Can you try cutting back your lights on time to around 6 hours with the whites...and have the actinics come on an hour earlier and stay on for an hour later.....so the total lights on will be around 8 hours.
Also can you check your phosphate levels. When the tank was first started up....did you notice a tank cycle....

I didn't actually 'notice' a tank cycle but did not test daily either. LFS has said that is pretty normal., but also said to keep the salinity at 1.023. Would the tank have not properly cycled with just LR? As I had mentioned, I do have 3 LPS corals that are living still and look totally fine. Should they be fed every few days with the foods I was sold for them or can they survive longer periods? Would they not survive on a tank that has not cycled?
As for the other questions, I clean my sock under the tap by hand and throw them in the wash every 4 weeks or so without detergent or anything. The snails I believe were Astreal (sp?) and bought 10.....six are easily visible at any given time. They obvioulsy move very slow and so they even have some algae growing on them  The 10 hermits I had I cannot see anymore (either all croaked or in the LR), but the cleaner shrimp is quite active and looks healthy. So 2 things: I should cut back lights to 8 hours a day total, say noon to 8pm and get more of a clean-up crew?

how much do you feed your fish? do you dose anything?
had this problem when i was loading my system with nutrients. just watch how much you feed your fish and cut down your photoperiod to 8 hours... and keep scrubbing.
