Hanna phosphorus ppb checker help

[Zigaz]

Hi i kept getting readings of 0 on my salifert test and i just got my self the hanna 736 ulr phosphorus and im getting mixed up with the numbers my reading on the hanna is 21ppb which is 0.064ppm so is this below 0.01ppm i know that everyone is aiming for 0.03 ppm how ever if did have 0.03 ppm would that show on salifert test? And How do i bring my phosphates up? Thanks

Is the tank newly setup with dry rock? I had to dose trisodium phosphate for months to get mine to even resister on the Hanna tester.

0.064 > 0.01

I would not do anything but monitor it for now. Other parameters and tank info would be helpful.

Perfect 0.06ppm or 21ppb.
It’s below .1ppm (not 0.01ppm which is a bad number) so that’s just fine.
I run 20-50ppb.

I trust Hanna only for this important test.

0.064 > 0.01

Can you explain the math please

Thanks so whats 0.01ppm in ppb and what 0.03ppm in ppb as thats what people are aiming for?

Sure, just move the decimal 2 places to the right, and the larger number is revealed.

The formula to convert from PPB to PPM is: PPB *3.066/1000. Looks like you have the right formula.

0.01 ppm = 3.4 ppb
0.03 ppm = 9.8 ppb

 

[Zigaz]

0.01 ppm = 3.4 ppb
0.03 ppm = 9.8 ppb

Are you sure is this is for the phosphate url not phosphorus url?

This is for the Phosphorus ULR.

This is for the Phosphorus ULR.

This is for the Phosphorus ULR.

And whats the ideal range in ppb

And whats the ideal range in ppb

In PPB, I run 20-40 for the first year and allow up to 80 after that. Occasionally, I need to mop up some phosphate with a temporary use of GFO if it rises above 80, week over week.

This includes a regular weekly water change of 5%.

And whats the ideal range in ppb

Something, not nothing, not too much. Stability is the most important.

Earlier someone suggested 20 - 50 ppb which sounds reasonable, but I don't know the size, needs, or contents of that system. There are a lot of different variables in play in EVERY system. I would not advise you on a number to chase.

Pursue equilibrium.

I think I saw a post where Randy said 3-33ppb. That’s what I shoot for at least.
