Phosphorus reading

[10-snales]

So I have a Hanna HI736 Phosphorus checker and need to know what range I should be at for a mixed reef, my under standing is that I should be between 26-39ppb is that correct Im a little mathematically challanged with phosphate readings.

Thanks

With phosphates, you're good anywhere from 1 (.003ppm) to at least 70 (.215ppm) in my experience (dont think my tank has gone beyond that but it may have). I didnt notice much of a (or any) difference in that range. I attached the conversion chart if you dont already have it.

I wrote a calculator to help with the math, you enter the phosphorus reading from 0-200 ppb and it will show you the phosphate value in ppm as well as the range of possible actual values given the accuracy stated by the manufacturer:

Awesome calculator that cleared up my understanding on PPM, I will be using it in the future....Thanks

I’d suggest aiming for 0.01 to 0.03 ppm phosphate.
