Building ponds for a herp greenhouse, part 3

Another turtle and tortiose pond idea I tried out was to use the large concrete mixing tubs available at home improvement stores. Suggested by long time kingsnake.com contributor Bonnie Keller, this option was one she had used one with the edges cut down at an angle to provide a slope down to a deep end.

At $14 a tub, I wanted to try one straight up because modifying 96 of them would be tough. And I was already looking beyond plastic ponds as likely the ultimate solution.

A rectangular tub that holds just over 20 gallons, it was smaller than the kiddie pools, but still so deep that it required more excavation time than I wanted to expend. I again excavated with a shovel and water hose to seat the tub properly, and again used the auger to great a sump area for drainage, and added a drain plug to the tub.

Though the ends of the tub had a gentler slope than the kiddie pools sides, it was still too steep for the turtles to get a footing to exit the tub. Again I added rocks to provide them entry and exit, but the Eastern Box Turtles had the same problems getting in and out. They would flop about, frustrated, fighting to get out until they found purchase on the rock pile.

Again this proved to be a "workable" solution that on a small scale could be usable once the issues were overcome, but scaling it to 96 pens would be problematic. This pond too, while still in use today, will be replaced by what turned out to be the eventual best solution.
