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.
Adam, the membrane is good for several years, it's definitely still good.
The other membranes have roughly 6 month life, which I'm still within. As mentioned my water is testing 0 tds and ICP test zero trace nutrients. As mentioned I have 2 tanks and one tank is excelling faster than I could...
