Does 1.5 ml vodka sound right for 90 gallol

[JOKER]

I have been dosing 90 gallon for few weeks now. Phosphate was from .03-.08 and nitrate was around 10-20. I was dosing 3ml a day the last week today is test day and phosphate is at 0 and nitrate is right at 10 so I cut dose back to 1.5ml. Does this sound right? Using 80 proof

It's a moderately low dose, but if nutrients are moving as you suggest, it seems just fine.

I would think 7-9mls would be the maintenancs number not even the nitrate drop number. You running macro algae and doing water changes?

I have some macro and also still doing weekly water changes. Havent changed anything but started dosing. I run gfo also but haven't changed it since started. My nitrate was just climbing a little and noticed some of sps weren't looking great. I restest tomorrow if can. I started at .5 for few days then went to 1 and kept increasing at .5 weekly till hit 3. You know I have been feeding different food come to think of it. Havent been feeding pellets. Maybe that's why phosphate dropped
