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 have a older ro setup, I don't know if the membrane is good I got it for free and I'm passing it on to someone in need. All you need is a 4th stage for the di and you are on your way.
