I've been pouring over retail sites and forums and I've seen conflicting comments comparing the Eheim 2211 vs 2213. I was hoping someone here with experience with them can help.
My main questions:
1. Does the 2211 come with doubletap connectors? I keep finding conflicting comments about this.
2. Would the 2211 have enough flow/power to use an in-line heater?
3. Would the 2213 be way too much for a 7 gallon 12" cube? Would using a valve on the return hose to limit the flow rate cause additional strain or wear to the pump?
Any advice would be appreciated. Thanks!
