www.bulkreefsupply.com has really good prices on gate valves (and lots of other stuff too).

anyone know where to find plans on building a herbie? Ive looked, cant find anything. OK I didnt look that hard, but help would be nice. Sorry to jack your thread!

Its really a simple set-up. Basically two straight pipes. I have fairly detailed pics in my build thread. http://www.canreef.com/vbulletin/showthread.php?t=40669 Shoot me a pm if you need/want more pics or to pick my brain....just dont pick too hard....I need what is left up there:mrgreen:

In the same vein I prefer the Beananimal overflow design over the standard Herbie for redundancy. Since setting up the Beananimal overflow it has saved me twice when I had 2 snails make their way into 2 different overflow pipes.
