+1 he's very good.
A LFS can have one made for you. I seem The Reef Shoppe customize and make sumps.
If your handy you can do one yourself. Petco having $1 gal sale. Good unitl Nov 5, They are selling 75 gal tanks for $75. Not all petco carry the 75gal. If you find one all you have do is add the baffles. A glass store can cut the size you need and all you have to do is silicone. Save you a lot of money that way.
