Had to say big thanks to this site, its members and xxl thanks to SantaMonica for inspiration and help. I was many years hesitating on seting up a marine tank at all. After I found this site, my doubts was gone. ATS idea seemed so natural and fluid to me , that after one more month I already have 16G tank siting on my table. Tank is custom made folowing my drawings and has scruber in back chamber. Also there is buble trap, heater and return pump. Thats all. Sometimes I put carbon , sometimes sponge if floating particles starts to bother my comfortable viewing. I still change water ocasionally with purpose to keep water chemistry on par. So very simple and easy to care system . As long as corals fell good, so do I.
The only problem is - corals grow too fast, so I start to bother about tank size.
This is how tank looked after 2 month after setup
