Phosphate level question

[Pbh-reef]

I just tested my phosphate level for kind of the first time. Hanna ULR phosphorus gave me a reading of 10ppb, which translates to 0.031ppm phosphate - is that ok? Truly ignorant here! Is there a good article to understand phosphate levels in the tank?

about .05ppm is just about optimal to most, and up to .1 is acceptable.

I used to do the math conversion from ppb to ppm, but found the below cheat sheet

that's perfect, don't let it bottom out and I try to not exceed 0.10 ppm in my own tank, but never want to be at true zero.

Great thank you!

If everything looks great in your tank, don't go chasing numbers. I have seen great looking tanks that have 1-3 ppb PO4 and great looking tanks that are closer to 80 ppb. Stability seems to be the key.
