好似見過得一個網友話用緊咋.

我聽過人 sell 都有d興趣，聽講好慳電同唔熱，ex75 同 p20 比係 670L vs 700L，5w vs 25w。

年電費以每度電 $1 計...$219 vs $43.8

I am using the Ex-90 for 2 months now........I personally thinks the price is a bit over from what I get. The motor is quite and powerful, but the bucket is weak(feels like it can break or crack easily without care) and the filter materials comes with it is not enough, and not as good to what I would expected from Tetra.
The bio rings looks like they are make from cheap materials and the bio balls...........( I am not sure if it works inside the filter as they are not being used for salt water and dripping filtration system commonly used in a salt water tank).
Bad try from Tetra trying to use the filtration materials to make up the quality of the filter. For quality and package the price tag is definately over marked unless you are planning to display the superior looking Tetra filter right next to your tank.
I have never used another external filter before but I think the option is wide open for you within the budget. Score from me is 7.5 out of 10.

From my final opinion try to understand what you want before you buy.
