Nuisance algae ID help

[JeanR]

I managed to get this nuisance algae into my aquarium a few months ago, have no idea where it came from. It is green, paper thin and grows in sheets. Maybe sea lettuce (Ulva)? I have a yellow tang, a fox face and a blue hippo tang and none have any interest in eating it so it keeps growing and growing. I just added a new aquascape piece (from dry rock) and this algae took right to it. It is easy to remove by hand, pops right off, but am looking for a good predator.

Thanks!

looks to me like Ulva (Sea lettuce) most Tangs or a lawnmower Blenny would clean that right up

That looks like Ulva. If you have a refugium the ulva will grow in the fuge and will be very easy to remove.

That isn’t really much of a nuisance in my experience, but I run a refugium. It may have come in off of chaeto or a frag. My Ulva came from Algaebarn

A tiny speck of that will grow quickly if there are nutrients to feed it.

I bought ulva to feed to the tangs but they don’t eat it. Turbo snails eat Ulva.

Manual removal with long tweezers may help keep it under control.
