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.

But overall I like your design, it looks like its part of that wall
Me and a member went in together to get the free shipping. So for me a short spine urchin and a coral and a Flame Angel, Yellow Goby, mixed snails for him. I've never ordered from them before but have read that they keep their salinity low for fish around 1.019-20
