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.
You would know your critters best, so if you see something that doesn't look "normal", the first thing I think of is the water param's. Have you checked them lately? What test kits are you using?
Every community must do an annual water quality report, and is public information. If you google it you should be able to see what they're using in your water.
Make sure they're not using cloramines instead of chlorine in your water, if so, you should be getting a chloramine specific filter. Check with the MUA.
