Wow, I cant believe how much the Tunze pumps under-performed. I was researching both the Tunze's and the Vortech's for when its time to get some crazy wave making flow in my tank - but that pretty much tips the scale in favor of the Vortech's

That being said, at least Tunze is stepping up, verified the results, and has said they will work to remedy the situation
