Hanna checker

Postby Vic » Fri 14 Sep, 2018 4:30 pm

Hi guys,

Are people using the phosphate hanna checker or the phosphorus hanna checker to measure phosphates?

I was speaking to hanna and they recommended the phosphorus checker as its apparently more accurate.

Hey Vic,

This comparison by BRStv sums it up pretty well: https://youtu.be/6SFMWRG0fRM

If using the phosphorus test you need to multiply the answer by 3.066 to convert phosphate.
Both only test reactive phosphate, neither detect organic phosphorus.

I have the phosphate one , it depends how minut you want to go , it reads in 0.00 so say 0.03 is where u want to be any lowere shouldnt matter and if your at 0.20 etc you know you have a problem, also saves having to multiply everytime
