I ran this on my freshwater tanks for years, don't know if its used for saltwater but I don't see why not. If you run your powerheads at a steady speed, this can save a few bucks when you have one go bad. You will not have to purchase the complete powerhead and control assembly, just the powerhead. It will take some knowledge of wiring and connector assembly. This is composed of a 12 or 24 volt power supply, and a voltage controller. I don't recommend using an old power brick because most are amperage restricted. Depends on your powerhead amp draw, you can run 2 to 4 power heads on this.
Power supply: 15 to 30 amp , 12 and 24 volt. $23
Voltage controller: 30 amp speed controller. will work with 12 or 24 volt. $10
When i mounted my speed controller, I drilled a hole in the side of the mounting cover for the knob. I used my voltmeter to measure voltage at lowest setting and highest to mark the cover.
On a side note this can be used to control a countless number of products economically.
