I have no idea about dose size, I just made it up. My "5 ml per 80 gal per day" dose was based on the very scientific fact of me happening to have a 5 ml syringe sitting nearby. But it seemed reasonable given the dosing info on the product label.Thanks! I might try smaller daily or every other day doses?
I didn't notice any direct effect on phosphates, only on nitrates.My NO3 is 1ppm or less, but my PO4 is .24ppm on average, so I'm just trying to lower it below 0.2ppm.
