I absolutely love mine, and would probably not have a 100 gal. and 55 gal. tank running in my house if I didn't have one! They make water changing so easy. You just hook the one end up to your faucet or outside water hose, set it to suck water or to add water, and you are off! The other end is your gravel hose, so you clean your gravel, and all that water goes down your drain or out into your garden instead of into a 5 gal. bucket! Then you just reverse the connection at the faucet and the water goes back into the tank! I add my dechlor as the water is going into the tank, and within a few minutes, you are done! No back problems, no spilling water, and it's so fast! My fish actually play in the new water as it's going in the tank. It is so worth every penny! The only problems I have heard have been that some folks with low water pressure don't get good results. Good water pressure is definately required for a python. Folks also complain about the connectors included with your python as being cheap and they break easy. That is true. I have finally purchased a replacement connector that is brass, and I have no more problems. I have also heard that the new python kits include a better connector now. Also, another issue is the water temp. You will have to adjust it just as you would if you were filling buckets from your tap to add back into the tank. I usually adjust it by feel. Of course you have no control if you are connected to your outside hose, but that is usually not an issue for me since I live in Florida. Just something to think about! It also uses more water this way. I think it uses 1 gallon for every 7 gallons syphoned, so just keep that in mind. Since I syphon my water outside to my plants, I don't worry about it too much. It really makes your shrubs and outside plants especially green!
