I have a 660 outdoor goldfish pond and was planning on purchasing the Python Fill Kit. I noticed that they now have a vacuum system to keep the bottom clean. Has anyone tried this yet? If so, would you recommend?

Also, regarding the Python Fill Kit - since I plan on using it outside for my pond does it connect to the faucet or can it connect to the water hose. Need to know to decide whether I need a 25' or 75' system.

Many Thanks!!!
