FW fert to rise nutrients

[aqva]

I'm dealing the second time with dinoflagellates (ostreopsis this time).
I'm in a situation of very low nutrients nitrates < 1mg/lt and no readings of phosphates
I'm running UV but is weak for my tank (already ordered a stronger one), dino are already on my acro frag

I have to rise nutrients and I'm overfeeding, I also have HGA issue that absorb nutrients, daily I manually remove what I can and I also reduced white lights to limit HGA growth
I'm overdosing ATI nutrition N P but nutrients won't rise up

I ordered Nyos NITRATE + and Nyos PHOSPHATE+ to a effective nutrients rise.
In the while can I use freshwater Easy-Life Nitro and Easy-Life Fosfo?
Nitro composition: 17.5% potassium nitrate.
Fosfo composition: 0.1% potassium phosphate.

Would be the potassium rise a side effect? Will this cause other issues?

Potassium will aid the GHA growth and the dinoflagellates I would recommend using sodium nitrate and sodium phosphate only adverse in this two is the alkalinity raise.

Agreed. Randy has stated the same many times that if your are not testing and monitoring for potassium, you might have a problem.
