Aqua Forest Reef Salt & Phosphates

[rbourgeois64]

Been fighting phosphates at .26 on my Hanna ULR tester for a couple of weeks now in my reef using Aqua Forest Reef Salt. I have tested the water coming from my RO-DI and the TDS is 0002PPM. So I decided to test my water change mix where I used Aqua Forest Reef Salt and the phosphates tested .26, the same as I've been testing in the reef. I'm very amazed that this salt produce is what I've been fighting to lower my phosphates, and in fact it's increased the levels every water change. Has anyone had this problem, think it's time to change salts, any recommendations?

As I mentioned in your other thread...

I'd be very surprised if there is significant phosphate in any reef salt mix. Maybe it is an error, or there is some other source in your mixing barrel.

What do you mix in?
