I've been there (at that forum) since the early days(about 2 years ago). Trying to explain a few concepts which they didn't grasp ...
of course all dismissed .
Oh yeah, as far as their expertise (experts) goes, flow is uninfluenced by pump, tube diameter and barbs, and aluminum is a better heat medium than copper.
So i just stopped posting.
Good people, but blind by "faith", as bill puts it.
Anyway, about the pump. Two things i'd like to point out, not apologizing anybody.
One, AquaComputer gets them from Eheim, disassembles them, sticks the dc power converter and reassembles the thing. I dont know if they're doing a "mediocre job", but i think it's lack of experience, it's not a "simple operation" , so boken plastic, damaged o-rings, etc, have appeared, in small numbers. Quality control is flawed , as it is a new product.
Two, the pump control is a good concept, but what kills it is the user interface. The "fill jumper" , stresses the pump , and probably toasts the dc converter if no attention is paid. Or something similar. I'd like to get one to test that, but 80 bucks... outch.
You can make a small comparison (small) with the MCP600. It has a few initial problems, but swiftly resolved. (pun intended
).
I'd let some time go to "see where it goes".
