I do have one, so I do know. It takes a hell of a lot longer than three minutes to properly install.actually thats exactly what i did shit moves to slow it's quicker to just use regular tap water and let it sit they way it works it filters all the no good water out of the black tubing and out of the blue tube fresh water comes but it was moving to slow i have no patience for it and it takes like 3 mins to put together if you had one you would know so beat it with the smart remarks
