I was also double billed recently, if my supporter status/features would of renewed automatically... I can't say for sure I would of caught the double charge. Anyways, I hope the issue gets resolved promptly.
Question?
Bottle on product says dose 5ml per 20 gallons once a week. For those of you who dose, do you add it in one shot, once per week? Or do you break it down to ml per day.
Thanks!
