if you are having problems with a green slimer, you are in no way ready to use pappone. You already dosed pappone once long before your system was able to handle it, bashed pappone as a PO4 bomb, and now you want to do it again? What is your PO4 at? Don't tell me you are ruling out PO4 without testing it just because you think a BM is doing a good job.
I'm dosing 379 ml per day of Randy 2 part in 220 gallons of water. I got to this number by testing. Where did you get that info about dosing a half gallon of Mg? I don't even dose Mg anymore.
I know this thread isn't about pappone but:
Personally, I would not dose pappone if all I had was a BM. I also don't think your system is mature enough. And if you aren't going to test with top quality testing equipment, you are going to have problems and blame the pappone... when believe me, it's you.
but you already know that.:biglaugh:
