C4 best HOB
ever get it.... only reason I could see getting a AC
is for the 110 but I would rather have 2 C4's. Had my C4 for like 3 years, always worked, motor never gets plugged up, easy to change filter media and remove carbon if needed.
Only issue I have had is if you unplug it sometimes you need to "poke" the impeller with you finger to get it spinning again.
the C series is basically the new upgrade to the AC
's but the AC
's were so popular Hagen didn't want to stop selling them so now they have 2 HOB
