We have a member in the Tri-cities that built a Custom Acrylic Tank. I am hoping he will post pictures of it. He wanted a larger tank to grow colonies of coral. It is estimated at over 420 gallons. The tank is 8 foot long, 2 foot high and about 4 foot wide. The tank has built in Coast to Coast with dual overflows on each end. I was able to watch tank being tested for leaks. I am hoping the owner will jump in here and post pictures of his new toy. Les do you hear me Big Guy?
