Still have algae issues in 4 1/2 month old reef tank >:-(

[newreefer_59]

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
