Awsome. Woohooo, Im excited about getting this done. Sounds like shipping is pritty decent time wise. Totaly excited about us doing the holes. I imagine their will be more tanks to come in the future that ill want drilled, :O) I will definilty go for the valve that comes apart like you said. Probably get alot of salt build up over time. And i had not even thought to add egg crate, great idea. I liked the idea of siliconing the glass in like Mark had said but couldnt think of a easy way of making the teeth so the egg crate will solve that perfect. I also like the idea of doing it all at home and not lugging the tank to the store for drilling. Thanks so much for your all you guys input. will put it to good use!

Ohhh that would suck getting through cutting ok to have it break on the other side of the glass. Will deffinitly do the tape thing, and we always have playdoh kicking around so will do that to! Thanks Swear i speant so long googling all this, should have just asked for advice right way, Hands on advice is always better !
