Lettuce Algae - How to get rid of it?

[Wolf89]

See if you can source a foxface! ulva is probably the most edible macro algae, more than likely it will be devoured

Ok, so I just bought 3 emerald crabs today. I already seen one eating some, so will see how that goes. Another LFS suggested sodium hydroxide to take out the algae, but not sure about that and not very comfortable with it. Anyone have use this to take out algae inside the tank?

How did it go?
I have ulva too and none of my CUC (snails, hermit and urchin) cares at all

Reviving an old thread here but I have sea lettuce (ulva lactuta) growing in my 13.5G Fluval Evo.

I took the rocks out a few weeks ago, picked all the sea lettuce off with tweezers, used a pipette to apply 3% hydrogen peroxide to the affected areas, let sit for 2-3 mins, rinsed off with saltwater and then returned to tank. It definitely did a job but I can see it reappearing in certain areas.

Would it be worth me adding 1ml of 3% hydrogen peroxide into the tank after lights out each night? I really cba taking the rocks out again haha.
