Who eats GHA?

[ExpensiveHobby]

After 3 years of zero algae I am suddenly dealing with clumps of GHA popping up. I run Macro and always have but for some reason I'm getting it now. Phosphate is up a bit more than usual and my RO still test around 2PPM so filter membranes aren't that bad.. For Christmas I am getting a reactor and a pound of GFO. My question is in the meantime what invert is the best candidate to eat GHA that is also reef safe. Only other invert is 1 peppermint shrimp. Only fish are 2 clowns.

Sea hares are GHA lawnmowers.

Just make sure your powerheads and overflows are covered.

Turbo snails have been known to eat GHA as well.

Sea hares for sure. Amazing and super neat to watch.

Hector's gobies will chomp on clumps of the stuff, for future reference.
