Does anybody have any experience with the "ECO-WHEEL" by Aquatic Engineers?

I had send the following questions several times to Aquatic Engineers, but
never received any responce.
To whom it may concern,

Unfortunately, your website is missing some vital information and is
presenting some inconsistent messaging between pages. Please answer the
following questions:
a.. The airpump is rated on your electricity usage page as using 175W and
at the airpump page at using 2.8A that would equal 300W; what is the
correct usage?
b.. In addition, on the electricity usage comparison you are omitting the
light for the scrubber that apparently is necessary and most likely be using
200W.
c.. In previous set-ups on your website there was no calcium reactor in
the system, now you are including one. What was the deficiency in the old
setup that prompted its inclusion?
d.. Assuming a setup containing mostly fish and some invertebrates how
many fish can your 12" eco-wheel support (number of average 5" fish or
accumulated length) if it is the sole means of water treatment and all the
equipment recommended by your company associated with it is used?
e.. How much water-change and at what frequency would still be required at
that quoted bio-load?
f.. What are the itemized prizes for the eco-wheel, the eco-wheel
lighting, the retrofit boxes and the airpump?
g.. What exact type of calcium reactor do you recommend, what is the price
and its maintenance requirements and cost?
h.. In case of converting an existing tank, would you recommend a
transitional period when the existing filtration runs parallel to the
eco-wheel system to 'seed' the eco-wheel?
i.. If so, what would be the recommended transition time and should the
phase-out of the existing system be done gradually, one component at the
time, or sudden all at ones?
