So I just tested my water with an api phosphate fest and a salifert phosphate test and got dramatic differences. On the api I got 0.25 and the salifert I got at most 0.1 but more like 0.05 which one is right?

Ok that sounds goodI don’t think the API reads less than .25......mine was .25 regardless of any mop up of organic through GFO, until I got a Hanna ch3cker which indicates .12

That’s good, I always thought I had really high phosphates so now I knowSalifert.
I use to use Salifert, then switched to the new Red Sea Pro because it is much easier to read low range. But the Salifert was accurate
