Looking at making a turtle pond from a 300 gal rubbbermaid stock tank. My son has been driving me nuts to move the turtles outside. I have a Little giant flex series ext pump w/strainer basket, pump does up to 3000 gph which i know is way overkill but what I have at the time. Probably use a rheostat to trim the power. Gonna use my Nexus Ez Pod for the time until I sell it. Now my idea is either to run a BD or cut a hole in the side towards the bottom and have the water pulled from there. I am not putting it in the ground so in case I wanna move it, also to try to keep critters from going in it. Only gonna fill it up little more than half way for now. I have 7 babies turtles that are gonna be housed in it. Any ideas or comments would be appreciated.
