oooo yer got 3x 305 and a 304 in the shead doing nowt could put a pair up that will put me leccy bill up a bit more tho

Connect 2 of the 305s together, you only need to power the 305 that is last in the line. Double filtration, only paying for one filter, thats how I filter my tanks!!

nice tip thanks curvi but dose the empela run in the second pump or sit idle?

Impellor only runs in the the one plugged in, the other stays idle. Intake from the tank should go to the filter that isn't powered, that then fills the 2nd filter (thro gravity from the tank) which is powered and pumps back to the tank. HTH
