My question is about a Little giant Pump I picked up for $5. It has a rating of 170 GPH. I want to use it to move water around a shallow pool (9in) which is the top of a bio-filtering system for a 3'X5'X2' bog pool.

I am building a bio-filtering bog as part of a larger pond project. The pond is next year, the bog is now. I am digging and lining a 3X5X2deep basin. Then installing a bio filter tube(Big leach pipe) in the basin. Over the tube I layer rock in decreasing size until only about 9inches of water is on top. My pump will pump water into the leaching tube which will force the water up through the rocks and into the shallows. The bog will have a short waterfall into the pump box. The process is a closed circuit.

Does anyone think my 170 GPH pump could work at all even for a year? Thanks in advance..... Cecile
