Sparky submitted a new Showcase Item:
Read more about this showcase item here...Medium aquarium experience. Only able to excavate 12” due to very large boulders. Hand dug what I could and settled for the tank pond approach. 2” HP Certifoam footprint. This gives me an extra week or so on both sides of winter. Ely MN has stretches of below 0 F that last for weeks. Usually at least twice a winter. -40 F happens. 2x4 pressure treated frame glued and screwed. Inner skin is 1/2” pressure treated plywood glued and screwed. Next the pump house.
Let me mention now this project was/is 50% planning and 50% scheming on the fly with what I had around or could come up with. Pump house has a 1.5x6” gate into the tank. Spillway is acrylics and silicone so the liner could mate to the gate. Spills through a .75” pvc grid into a 6 gallon waste can with my pump. Pump house has a solid pressure treated floor (2x4s) with overflow drains. Water travels through the framing into the garage where...a picture is worth about $90. Experiment. Not a new idea. Effective. Cheap. Returns to tank via a mini bog and water feature. Outside tank is combination of scrap, bought and milled materials. This will be a work in progress hopefully. On to bigger ideas!
