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 been doing a ATS for a few years now, and I like this DIY project.
I have a few questions - How many inches is the screen? What kind of lighting are you using on it? How long have you this ATS up and running? Long enough to get algea?
