Hi, I've posted my ADA 60-H tank, 60 x 45 x 45 cm for sale. Comes self-drilled with eshopps brand overflow and acrylic eshopps sump. Cabinet is honestly quite worn down so you don't mind changing the cabinet, you'll have an awesome tank. Contact me if keen, thank you!
it depend what is the purpose of using the ATS, if the purposes is to reduce nutrient then it works.. however skimmer work as a mechanical filtration to remove waste from the water and also provide oxygen in a reef tank which is benefit to the system
