Need help with water parans and developing algae issue

[Djasak]

What's up guys, I've just finished doing my series of tests and I have a couple values that are high. I would normally just do a water change, but I just started seeing a couple different algae outbreaks that have me a little concerned. They're small isolated patches and I dont want to start stirring things up in the tank and make it worse...so what would you guys do in this situation? The outbreaks I'm seeing are cyano, diatoms, and dino. These are all presumed based on my eye and experiences from past algae outbreaks in previous tanks. I do not have a scope to confirm what I believe these algaes are. Params are as follows:
Salinity: 1.025
Nitrite: undetectable
Nitrate: 3mg/L
Phosphate: 2 mg/L
Mag: 1560ppm
Alk: 16.1 dKH
Cal: 460ppm

Mag, alk and cal were tested using the red sea test kits.

Phos, nitrite, nitrate were tested using seachem test kits.

Thanks in advance for any help.

P.S. I wasn't sure where to post so this is also posted in the reef chemistry page.

First you will need to fix the dino problem. If you go the black out routine it will get rid of the cyano. Diatoms usually fade out in a new tank
