Well, let's see. Your tank is what 13" wide? If you break mine up into 13" sections, your full 13" will look better than any of my incomplete sections and thank you i have to drain the tank and let it dry out. Then i can do touchups, and adjustments. Not keen on the right side water fall. And i still have a trick or two up my sleeve that needed to wait until now before they could be built. I figure planted not this weekend, but by the end of next weekend. <crossing wee wittle chipmunk paws>
