Phosphate parimeters

Hello i just got my hanna test kit my nitrates are 0, calcium is 510, phosphates are 0.20 wondering whats the correct phosphate level for a mix reef tank got mostly lfs and a few dps

0.2 is ok. Nitrates should be above 0.
0.1 po4 is a good target.

There’s not really a “correct” level. My tank likes .0X. Anything in the .1X and above and I start to see undesirable algae growth, yet others have stunning tanks at much higher levels.

I'd recommend getting the nitrate above zero unless you are confident your tank has a lot of other N sources (such as ammonia, organics, or particulate foods).
