Algae ID help

[SWFiend]

This Algae taking over rocks need help id

I have this velvety slimey globular algae

It grows on the rocks thick and will grow right over corals and doesn't just blow off the rock with a turkey baster like cyano will. I had to intensely scrub it off with a tooth brush

I have very high flow in the tank and when I scub this off it's like sediment aswell under the algae

I run have started running rowaphos but have had a fuge with chaeto phosphate is .01-undetectable on tests prior to adding the GFO idk how to rid my system of it... It kicked off after doing a 20gal water change with fritz salt vs my normal IO

Interesting..
Can you snap one more pic without the blue lights on?
what about nitrates?
type of lighting?

 

[SWFiend]

Lighting is Ati t5

Unfortunately can't turn off the blue as my bulbs are

3 B+, 1 purple + 1 Aqua blue special and 1 fiji pink

How old are the bulbs? Maybe time to replace them?

+1. I was about I ask the same thing

 

[SWFiend]

Nitrates are low I actually have been told by my friend to bring them up for my sps

 

[SWFiend]

Bulbs are only 6 months they get replaced at 9months religiously

Maybe a type of leathesia ??

Maybe is more of a sponge?

Can you pull a rock out and get a better pic?

 

[SWFiend]

I can how should i take the pic? In a deli cup with water? Dry?

It's not a sponge it releases bubbles by the end of the day

I cleaned 99% off the rock yesterday but saved a patch to be able to take pics for people

My friend JW of two guys corals also believes it is a bacteria and I should put a UV on my system. I have roughly 120-140gallons actual water volume how big of a uv should I use?
