This is for a used Apis 300 turf scrubber. It’s a total animal. I ran it on a heavily stocked 310 gallon display and it grew algae and pulled nutrients like crazy. Had an issue with the lights and the company sent me two brand new lights that have about 6 months on them. Live in East Northport and work in queens so meet up is very flexible. $250. Has two Led light boxes. One on each side. They have their own cords so you can run them together or independently.
