I am not sold on the whole micron filtration, this means you have to use their filter and replace it, costly on top of an already costly filter. I run a Canister filter and I use filter pads, that I can take out and clean, even using the micron filter pads I can take it out and clean it.
Several months back I posted a thread on getting 1 micron cleaning using a 3 stage filter that stepped down from 10 to 5 to 1 microns. All this using just 3 normal 10" filter housing plus the appropriate filters. This system could have been built for 30 bucks, and you could get a 40 pack of filters from eBay for 40 bucks that's enough for you to change filters every 5 weeks. So 70 bucks got you the filter and close to a years supply of replacement filters. Then only cost 40 bucks a year after that, I promise you the Hagen micron filters will cost far more.
As far as the bypass free my system would also be bypass free, bypass free is only important in mechanical filtration. Also the temperature monitor? you can buy a digital monitor for 20 bucks from petsmart, or even spend a couple bucks more and get a nice wireless on.
And unless your running SW the salinity meter is pointless. You could spend the money and get a nice Ehiem Pro3 or Pro3E, or a Emiem with built in heater.
