Ulva lactuca taking over display

[painter1982]

Any advice on getting rid of Ulva lactuca? It’s growing on everything in my display that doesnt have coraline already (60g). From top high light areas to bottom low light areas. My yellow tang eats some of it. I have over 20 trochus snails, 5 small turbo snails, 100’s of baby snails, likely trochus. 10 blue leg hermits. A couple of blennies or goby that I’m not sure of (came with live rock). They eat algae.
Phosphate .03 to .08 range dose neophos
Nitrate 4 to 6 range dosing neonitro
Alk 9.0
Salinity 35ppt
Calcium 440
Mag ? Was good last icp test.
I dose AFR daily 57mg
I have sps coral that are growing good, I don’t really want to limit light. Am I just going through a cycle? 8 month old setup.

A possible solution is adding a lawnmower blenny. I had one for years and it even ate bryopsis.

Anyone have any ideas on where to source some cowries in the U.S.?

I’ve been looking. No one has them that I see. Reef cleaners said they “may get them down the road.”

Ah, sorry guys.
They are reasonably readily available here in Europe. I assumed the US would be similar.

I recently found a good deal and bought 40 of them for my system. My frag tank was really bad and they are going to town there steadily munching down the Ulva. About a month in, its still present but not overgrown anymore.
