Hanna Phosphate Test

[kissman]

Which is the best for Reef 736 or 713?

 

[James77]

The 736, the ultra low range, is mor eideal for what we need. It measures in ppb, and is then converted to ppm, so its range of accuracy is more precise. IE +/- 5% of a ppb measurement will be more precise than one with ppm.

I have used both, and have had no problems with them or the use of them.

+1 Well said, Jim.

Is the API Phosphate test any good? Petco has them at $1 off. So $9. Not too bad.

API is very unaccurate. If you want good kits that are realiable use Salifert, and a little cheaper is the new Red Sea Coral test kits. Cost a little more upfront but then you can buy refills and ends up being a lot cheaper. For Phosphate I am learning Hanna digital

Does the 736 come with the instructions on converting to ppm?

I use the Hanna 736 and it works great. I like it. Very accurate.

Yes, and it's a very simple formula. Off the top of my head I think it's multiplying by 3 then divide by 1000.
