What is a good algae grazer?

Your overflow should be protected with plastic mesh on top to stop all your future creatures from getting in there.

Sea hares are supposed to be able to "ink" like a squid, and probably not the best creature to have in your tank if/when they die (they don't live more than 1 year I think) but I had one in my 50g to clean up my hair algae and when he passed on I didn't have any ill effects on the tank, so your much larger tank would not be in much peril I would say.

You dont have much for corals which is good because they can knock frags around pretty good.

If you have 3" hair algae, a sea hare is a good choice. You will definately need snails as well though, add 20-30 at a time, you dont want to add a ton at first and have them die off later due to lack of food, but you will probably need 100+ when you get your full reef action on!

Oh, and you might think they are ugly now, but they grow on you. So ugly they are cute!

Okay.. I've battled HA for a while since starting up... and IMO the best thing to use for it is a Sea Hare. Both that I have owned did an excellent job in removing it. The bad thing is : They are big, and they knock stuff over a lot .

I need to try snails though, as sea hares just aren't good for reefs because of their diet either

Also, LMB's really do not eat hair algae, at least IME. They'll take a bite at some of it every now and then, but they definitely won't get rid of it.

Go with the Sea Hare, and trade it or sell it out as soon as all the HA is gone ! JMO.

I do have eggcrate at the top of my overflow but was thinking they might be able to either crawl over top or squeeze through it. Any comments?

Small snails, crabs, shrimp and fish will go through eggcrate. If you stick to larger stuff it'll be ok.

Gutter guard works good for tying to the eggcrate with zipties. (you can find this at your local hardware store) It's basically just a black mesh material.

[TheReefGeek]

If you have eggcrate that is good enough against a sea hare. If you run powerheads make sure there are covers on the intakes.

There is smaller mesh stuff than eggcrate that is better though

The inlet on the Tunze streams shouldnt be a problem I hope?... I beleive I have some gutter mesh - Black plastic diamond mesh stuff.. I think I will apply some to my overflow.

[SeaHorse_Fanatic]

Those stream type powerheads can & will kill sea hares so make sure they're covered. Any powerheads can suck up an unsuspecting sea hare but the Tunze & Seios are so high powered, they're even more of threat.

the lawnmower blennie is a film algae eater, won't make any difference in the hair alage at all.

I actually have a 20gal with lots of hair algae growth. I put this growth into my FOWLR tank.My fox face rabbit fish and my blueface angel will clean a rock in about 2 hours. The rabbit loves all types of algae whereas the lawnmower in the same tank would prefer for me to feed it .

With your tank being so new and if you don't have many corals yet you might consider cutting back on your lighting period (if you haven't already). You didn't say whether your live rock was cured or not when you got it. A number of articles I've read suggest slowly raising your lighting period on new tanks from 4 to 10 hours over 6-8 weeks.
