Here is a poor shot of the tank with the cutting board bottom installed. Nice glare, I know!!
Here is just over $964 in water movement. These are in addition to the two 6100's and the controller which I already have. No wife and no kids makes decisions like this a no brainer!!
Here is a crummy shot of the front. The doors are not on and the top molding will not be put in place until the tank is set up. The tank weighs 500lbs empty and is a bear to move around. Having the molding in place would compound things to the point where profanity would run wild.
Here is the rock that has been cooking in my garage for most of the summer. All of it has been drilled with a 1/2 inch masonry drill bit.
This is a single idea of what you can accomplish by using this method. Keep in mind that these are a few small pieces that happened to be lying at the top of the containers; the rest is much larger and more shapely.
I'll take some pics of the holding tank tomorrow, once I get it set up.
