I finally received my PMDD in the mail yesterday. The dosing for it was recommended to me such that: 1/4 cup of powder to 500 mL of water. Then 1 drop per gallon of water per day. You could go 2+ drops per day, but seeing that my CO2 tank is not here yet and I am just learning I will start with 1 drop per gallon per day and see where that takes me. But with that being said, is any of that assuming I do any specific water changes per week or something? Anyone lese use PMDD? Thanks!!!
