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.
Heres their site. You can also brouse the old groupe buy forums to get better ideas on what questions people are asking. For instance, go to forums, groupe buys, then look under A W I discussions or questions.

See if you can get him to go to Ed's meeting in Sept. Tell him you want to show him Ed's inwall tank so he can get some ideas for his. I think once he sees a few established tanks, you're in with salt in the 125. ;D
If it's any eaiser, Home Depot sells acrylic pieces in all different sizes and they have caulk in a red tube that adheres to both glass and acrylic. The caulk would be right with the acrylic on the upper shelf.
I'm suggesting a U tube design. I've had all kinds and that one lasted the longest. Do you need that one. Probably not. You will most likely upgrade tanks before any overflow breaks.
I would go with the Overflow tha Mott (Tom) is linking you to. I have that one on one tank and the other one thats molded on another tank. I don't like the molded design because theres no way to clean up under where its molded. It gets soo dirty in there where it clogs the hole to the siphon...
