I've only used Hagen's(Aquaclear) and Koralias.

I've got 2 Hagen 802's that are 20 years old. Both my Evo Koralias quit in just over a year.

Not sure about their consumption, but the Ecotech Marine ones that work thru the glass meaning no cables in the tank are very cool, and priced accordingly. Tunze are another good brand, maybe do some googling and let us know what you find.

i have looked into that pump but $40 pump compared to a 235 is a lot of difference.. i understand with the driver outside the tank looks good but i rather spend on other products instead. also my aquarium is 1/2" thick glass.... thanks
