Super High Phosphate

[Ara29998]

My RO-DI shows .04 and when I measure the phosphate it shows .04 after adding salt to the RO-DI it shows .11 .
Now my tank shows .44
Any idea what I can Do?
My tank is 30G.
I don't have sump but I transferred my hang in the back filter to refugeium and I have some algeas there. And I have a 360 filtration system.
And to mix the water I use Red Sea Salt. My salinity is 1.26 and PH is 6.7

How much are you feeding? Feeding a lot can lead to high nitrates and phosphates. Phosphates at .04 isn’t really anything to worry about it’s more when it reaches 0.1 where you would want to do a water change or find other ways to fix it and bring it down. A little bit of phosphate like .04 can actually be better for corals, if you have any, compared to straight 0 phosphates. Your ph is a bit low though but that’s just my opinion I can’t tell you if it’s really bad or anything but usually people tell me to have ph around 8.
