Orignal post made by Rod Neil(Shovelcat44) on December 24, 2002 Here is the tank that I built out of a 125qt. cooler.I used 1/2" pvc pipe. The top piece has 1/4" holes drilled about 1" apart. It is hooked to a 500gpm pump. I have ran a wire from my truck to run the pump while I am driving to the lake or river. The coolers were $35 at Sam's Club, the pump was about $15, and I have about $10 in the pvc and clamps to hold the pvc in place.
