When I built out my mixing station, I was very tempted to go with a Vectra, but to save money (after buying storage containers and all the fittings) ended up with a Danner pump. I hate it... its so loud and vibrates a lot. my Vectra in my tank runs so quiet. But I also looked at Iwaki, Pan World and Reef Octopus. If I had to buy one again, Id probably go with any besides Danner, depending on the size needed and funds available.
