Gross Algae taking over

[jokerjohnson]

Over the last few months, this stuff really took off. I’ve been cutting back on feeding, 40 gallon cube and conduct 10 gallon water changes ever 7-10 days ALWAYS.
Have a 7 stage RODI filtration that is reading 0 TDS, using fritz salt (changing to aqua Forrest once this last box is gone)
How can I get rid of this crap?
And can anyone positively ID, hair algae, turf, and bryopsis?
Thanks

GHA. There could also be a bit of chaeto in there.

Chaeto?
I’ve never put chaeto in here before, would it just grow on its own like that?

I would scrub it off the rocks with a new toothbrush and siphon it out. Then add two pincushion urchins and have about 40 astrea snails total.
