Assure you are getting accurate not false readings by taking a water sample to a trusted LFS tha does Not use API kits and see what they come up with.
If accurate, feeding of reef roids will elevate phosphates

Thanks vetteguy I use Hanna checkers for all parameters

I always tell people you probably don't have 0 phosphate in all actuality. Our test kits only measure like 2 percent of the total phosphate as many of the phosphates are bond to rock etc. However to raise them without feeding more, especially flake or pellet, you could use neophos by brightwell. I use it to maintain my phosphate at .04 and works really well, just follow directions

Which Hanna?

If it is the HI774 and you get none detected, I'd either feed more or dose phosphate (I recommend food grade sodium phosphate from amazon).

Too low of phosphate risks dinos and doesn't serve corals well.
