I use my Aquaclear 110 powerhead I put a hose on the adapter that came with the pump. The hose I use is that black hose that goes on the drain tube to your washing machine I believe that is 1" hose. I can empty my 200 gal in under 15 minutes, probably closer to 10 minutes. It is one of the best things i have ever done concerning maintenance. I keep saying I am going to do a video so everyone can see how effecient it is.
