Deficiency?

[freshtosaltwater]

I started noticing my Scarlet Temple looking rather under the weather in the last few weeks. I am trying to figure out how to help these guys and bring them back to life. Our my phosphates too low? I have some green/brown algae on the glass corners & substrate level that seem to always return after a scrub with the magfloat.

Any help is appreciated!

PH: 7.4
Amm: 0
Nitrite: 0
Nitrate: 0.1
Phosphate: 3
