Need urgent help with GFO please

[Rohirrimus]

Hello reefers,
I’ve got some crazy high phosphates, 0.25 to be exact.
it was probably from LFS water, I already ordered my own rodi waiting for it to arrive , but I need urgent help with Fauna Marin PowerPhos GFO since honestly their instructions suck.
This is the product:

my questions are:

1. dosage is specified in ML instead of grams, is that correct? I’ve never seen a dosage of solids be expressed this way
2. Do I need to change it regularly, or after 5 days?
3. how do I know how much to put for the amount of phosphate I’m starting from ? Is there any chart or something?

I don’t have a reactor for now I just added it to the filter, but hopefully somebody can help me with these questions. Thanks

That will not do anything to nitrate. This is for phosphate.

Do you mean phosphate?

That's not crazy high.

Sorry I am a bit tired and made a mistake, I meant phosphate , N03 is fine, in fact I have to dose it daily to keep it above 0. I edited my post to make it clear
