well this is odd... I cannot imagine trying to clean my 6' tank with this...
looks like a good tool for the power-head though in the video it didn't seem to get the hair-algae off...
I would consider trying the 1/3hp version.
way to make money though.
buy a 5.99$ toothbrush, change the label, sell it for 3x the price, take the money and laugh.
May be it would work on my cat.
