Here's my story.
I have a 215 gal reef (http://home.comcast.net/~fish.tank/ )
I'm needing to improve my protein skimming and circulation in a major
way.
I've decided on an A. E. Technology ETSS 800 skimmer & UHF Pro 72
Reef Sump.
Now I need to pick some pumps.

I am leaning toward an Iwaki MD55RLT for the skimmer and an Iwaki
MD100RLT for filter and circulation through the chiller.

Questions:
1) Are the pumps sizes sounding good?
2) Any thoughts or experience with the BlueLine HD Pumps HD100 and
BlueLine HD Pumps HD55 ? They are advertised as:

quieter and cheaper and "BlueLine HD Pumps "Our best, most reliable,
cost effective pumps for applications requiring heavy flow without all
the noise" These pumps are designed and built by a former chief
engineer from Iwaki-Japan."
