great for large large tanks. 75 gallons or better this might be a good investment for the long term it recycles the water in the tank for less water changes can get a couple of extra weeks of no water change and you can hook up water to this also to add water to tank i just got it and it works great . you can clean for a long time because you are not limited to water running out . water goes back in tank. saves good bacteria. and helps filters last longer . save money on media and it realy sucks the crap out of the tank. not like the python. i use the python just to take water out of tank and put back in it is not a good cleaning vacume. take a look ! and you can clean tank any time you want with out a water change wich is great!

After having purchased one of these, I was a little bit upset because I had read some bad reviews. But having used it - I can say that it works as advertised, and I'm quite pleased with it. It works like a charm and doesn't make a mess (provided you follow the instructions and lubricate all the "o" rings before each use). Definately would recommend it to others!
