Green rocks when lights are off

Only when the lights are off. When it’s on, it looks good.

Phosphates: .25 (it was 1.0 to .50 a month ago)
Nitrate: 5.0ppm

Tank is considered new because I took down my system for a week to change the plumbing because of leaks. The rocks, corals, and fish were kept in a brute trash can for a week and sand was completely replaced.

This was late January of 2019.

This is with white lights on

Looks like gatgoe. It’s the same algae that grows on your glass that we scrape off with cleaner magnets. Totally normal in my opinion being new rock.

Totally normal. Just keep slowly working down the PO4. No drastic measures needed in my opinion...

Just normal , be purple soon enough

Looks normal to me.

Just work on bringing your PO4 down SLOWLY to.08-.1 and it will be fine.
