Nothing wrong with their workmanship, just poor quality glass and even more poor quality customer service/attitude.

+100

Another bump for Dave and Concept. He's built all the tanks on my 1000g system so far and they've all been excellent.

Ditto on Dave at concept. Very pleased with my 180 eurobraced starphire front and my sump. Even friends who have no s/w experience call it a sexy beast.

Dave at Concept built all the tanks for my setup. Outstanding quality. He's the only guy I would ever go to.

I disagree.

When they made my 67gallon corner over flow tank, 1 of the drain holes was drilled so close to the edge of the overflow that the bulkhead couldn't be installed without modification.

I ended up trimming about 1/3 of the bulkhead's flange away in that area.

The tank is 3/8" glass and it was eurobraced with 3/4" x 4" glass on the top.
Accessing the overflow to install the bulkheads and pipes was impossible without removal of the sides of the brace.

Zero support from them to fix it.

That is all!

Have you heard of Concept, I am sure someone will mention them eventually? :) They are pretty good. Call Dave and he will set you up.
