I got it today, I am planning on using it on the new 150 tank. But tested it today on my 75g. I had to turn it down to 40% because it pushes allot of water. The controller is fairly straight forward, but I didnt really like the dial.
Controller allows for schedules, so you can have different patterns and flow % anytime of the day. Controller has a micro SD slot, not sure if its for saving profiles or ?
Over all seems like a good purchase for the $.
I would recommend not removing the protective film on the magnet. If you do, it sticks to the glass pretty good.
