Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I liked it ran it for about a year dosing trace elements. Never gave me a problem the app is easy to use and the pumps pretty accurate. Just have to use check valve on the lines that's it . I have a dosing container too.
