It is fixed now. I'm not very techy and I'm finding the app confusing to use. It is not intuitive to me. Anyways I started setting up the light to have it at 60%. I pressed Save As in Customize. I want to delete this and try to use the the preset Buce at 60%. On the screen there are four options Save As, Load, Preview and Reset. Can someone walk me through this and make it very clear every step I need to take please? Chihiros WRGB II 90, mature tank, aquasoil, fertilizer and CO2.
