Is this 'hair algae'?

Hello! My hair algae problem is definitely under control. I added a Mexican Turbo Snail (who really lives up to his name!) that just plows through all of the algae on the rocks and the back wall of the aquarium. He never stops working! I also added a Lawn Mower Blenny (I was advised that this wouldn't be the best idea because my tank was so new and eventually he'd run out of food, but I guess I got lucky and he still seems fat and happy). I think it's kind of a hit or miss sort of thing with LMB's...some are picky eaters and others aren't, I just happened to get one that wasn't picky and he doesn't seem to run out of food. He even likes to sit on top of the Mexican Turbo Snail or one of the large Scarlett Hermit crabs and take little bites of algae off of their shells. He's been in the tank for a little over a month now. It's only a 30 gallon tank, so between the snail and the the LMB, they are doing an excellent job cleaning up the rock and back wall.
I also have 3 large Scarlett Hermit Crabs, I honestly can't tell if they do very much. I see them climbing on the rock, but whether or not they are making any kind of a difference is a mystery to me.
I think the thing that made the biggest difference is simply plucking the air algae out of the sand. It's a little time consuming and of course I would never get it all, but it REALLY helped clear up the problem. Hair Algae is so light and because of the water current it can easily drift away if you reach in and just pull it out. So I took a clean glass and placed it on the sand bed in the tank, and then where ever there was hair algae I would collect it (by taking a pinch of sand) and deposit it in the glass....that way the algae/sand would float to the bottom of the glass and not escape into the water current. After I got most of the hair algae out of the sand, I would just slowly pick up the glass (with the hair algae and sand in the bottom) and lift it out of the tank.
I keep my lights on for only 6 hours, but I'm considering increasing it an hour because of some Zoa Polyp coral that's been growing on my live rock.
I won't be adding any new fish or inverts for a couple more weeks (see my thread on the ammonia spike I had last week). I just need to let my tank sit and not make any changes for a little while.
When I am ready to finally add something new a sand sifting star fish sounds interesting....though I don't really know very much about them. I'll definitely have to do some reading and research before I add anything (that's one super valuable lesson I've learned thanks to SWF.com!) How mature is your tank? What kind of requirements does a sand sifting star fish require? Do they help eat hair algae? If I ran out of hair algae in the sand, what else would it eat?

Glad to hear your problem is under control. My tank has been up for about 3 months. I think I am going to get a mexican turbo today to help with rocks. The sand sifting starfish basically moves around on top and below sand. I'm not too sure about star fish and compatability with other stars but the sand sifting one seems to get along with everything in my tank. They eat all kinds of left overs and the sand looks pretty good. I would get an orange spot goby also, they are cool to watch eat the sand and filter back through their gills.

Thanks for the advice! I'm definitely going to look into those two. I was just starting to think about what to add next, and this gives me a starting point from which to research and then make a decision :)

Just FYI, sand sifting starfish usually starve in captivity because eventually they will run out of food. Especially so in our home aquaria.

Manually removing and starving the algae of light is a temporary solution. It is also somewhat difficult to totally control hair algae with a clean up crew. You really need to limit the nutrients that are allowing large scale growth of hair algae. Most people with reef tanks concentrate on limiting phosphates to control hair algae since phosphates are bad for stoney corals even in relatively small quantities.
Common methods for controlling phosphates are frequent water changes, rinsing frozen food, not using flakes/pellets, not over feeding, macro algae, algae turf scrubber, protein skimmer, phosphate absorbing material (Granular Ferric Oxide) and not using tap water. Usually people need to use a combination of these methods to keep their phosphates down.
