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 really can't see from the pictures, but it's ALL over my tank - including the walls. From my experience, it grows in mats and just expands and expands for as long as it has some type of object to grow on.
It grows over my calpura (no kidding..), rocks, tubes, glass, overflows. About the only thing it refuses to grow over is sand and heaters.
