Thanks for the info. Will check into that when it's time to buy a new pump!
I thought aquariumpros.com was the same thing as aquariumpros.ca, but judging from the prices there, those aren't Canadian prices.
For a moment I thought I had found "TheMostIncrediblePricesEver(tm)" on pumps! ("Wow!!!! A Mak4 for $150?! I'll take FOUR!!!! ..... oh crap what have I done....."
