Sorry for the confusion folks
. I listed "mj1200" in the first listing because I had forgotten that they make different sizes and just assumed they were the same as mine. The owner corrected me when I called him for an update and said that his are infact 900's.
Also, I am pretty sure that this is the brand of his wave timer:

I will double check by having him read the name off of it - he packed it up a few months ago and has to take it out of storage (I advised him to run the powerheads full-on until he got his sump set up and added some additional flow... which unfortunately never happened...
Thanks,
