I'd like to get a few other reefers experiences with this stuff when used against bryopsis. Maybe theres a pattern in there. I have three, the first of which i don't have my nitrate and phosphate numbers for, but when i dosed tech m, about 100ppm a day, 4 days straight, i also had gfo running and was carbon dosing, i'm pretty sure my nutrients were low, bryopsis melted away. Second time, i raised it for about 6 days in the new tank, 100ppm a day, my nitrates were between 5-10 at this time, phosphates went in between .02-.08. Didn't do a thing for it. After a month or so i added gfo and started carbon dosing again. About a month later it wasn't dying off, but wasn't growing much, no detectible nitrates and phosphates. At that time i dosed tech m for about 3 days, the first time on this tank i unloaded 2 gallons when it had no effect, this time i went with one gallon, all the bryopsis melted away. If i had to guess i believe it's a combo of the two, starving and raising mag, but i'm curious as to other peoples successes and failures with it and what exactly they were dosing and what their nutrients were at. My carbon dosing was using cheap vodka.
