I know someone who is running a reeflo also on a 150g tank but it was AC Hes had it for about about 11months or I think with no problems. Its the swordtail model Im not sure. But I think having a DC pump is the way to go nowadays allot more manipulation with the speeds.
I used to run a gen-x pcx40 for my pond years back when I had the filtration in my garage. I ran it for about 2.5 years untill I took it down it had like 22ft head. And was priced very well.
