I've got a basement sump, and pushing probably close to 12'-14' of head. I looked into those blowhole pumps and there doesn't seem to be very good reviews on them. I ran a Laguna pond pump on mine for a year and it was a really good little pump but took a fairly large foot print in my sump. I've since switched over to an external Reeflo Hammerhead. It was a bit much for my 77 gallon display so got the Barracuda impeller and it's just right. When I get my 210 up and running I'll put the bigger impeller back in.
I have no experience with the WATER BLASTER HY 7000 so no comment there.
The Waveline pump came out after I got my Reeflo. But from what I've seen and my conversations with the manufacturer, it'll do the job and will probably be my next pump. I know Grizz is running a couple of them and so is ... hmmm I don't remember who, but I know someone else is
Hopefully they'll pipe in here.
