My Frag Tank has no Fish or Inverts so there is no added food or waste in the Tank.

I use RO/DI Water.

And my light is just a Double T5 (Not even HO) .

Aquarium Lighting Fixture Coralife Aqualight T5 Dual Linear Strip Fixture, 2X14 Watt, 24 inch


So I figured that I would have no Algae at all in my Tank.

But I realized today that there is Algae on the Front Glass and some of my Frags have Hair Algae at their bases.

I was wondering what I should do for a Clean Up Crew for my Frag Tank.

All my other Tanks have Hermit Crabs but they always tip over my Frags.

I have never tried Snails.

Would they also tip over my Frags?

What do you guys suggest to get rid of this Algae Problem that I have?
