Well reefneck, i know how to build a sump and I know what's required of it, but I'm not building one for this tank. Don't want to bother with it right now as I have all of the components of the tank now, except the skimmer. My time is occupied with building another fish tank projet which does incorporate a sump.
And Gump, I'll have to disagree with you there as I have been running a BakPak 2 on one of my tanks for over 4 years now and haven't had a single problem and know many people who have no problems running HOB. All i was asking for was a model that people had experience with and would reccomend...
