Anyone own one or has experience with them? Slowly putting together my 120 gal and i was looking for a quality canister filter, and since i'm looking at hydor's products! The in line heater to be exact. (i'm one of those people who like to stick to one brand) They look decent! Look well built just want to hear someone else's opinion! Their biggest one is the 600 which does 290 gph, 5 trays, filter volume 13. qts. Also i plan on having one or two sponge filters in the tank.
