Phosphate and nitrate levels

[Jgill70]

Hello. I tested my water today and my levels are as follows:
Calcium 425
Alk 8.1
Phosphate .06
Nitrate 0

My corals do not have much color and was wondering if any of these levels could be the reason. If so how would you correct it. My tank is almost 16 months old. I’ll attach a pic

Yes, feeding more or dosing some form of N is a good idea in this scenario.

What should my nitrate level be

What should my nitrate level be

I recommend 2-10 ppm, with levels above that range better than below it.
