This is my first attempt at building an ATS. The downside of most ATS imo id that cleaning the screen seems like a hasle. So I wantend to build something with an easy to clean screen. So far nothing out of the ordinary. My version has 2 spraybars on the side. They do get plugged so I clean them with a toothbrush whenever I clean the screen. The screen fits in the middle so it’s easy to remove for cleaning or getting some algea for my docters. This is the setup in the sump. The screen is 13x27cm and is lit from two sides, each side is equipped with 8x 2w 660nm LED’s 18hr per day. Water supply comes from a take-off from the overflow. One week of algea growth. I feed one cube per day and the ATS has been running for six months now.
