Hi folks, I'm putting together an ATO system for my wife's Nuvo 8. Below is the tank I designed. I'm just beginning the search for the pump and other associated hardware. I'm a bit overwhelmed at the choices available for pumps & controllers, ect. I'd welcome any advice in this area as well as any ideas for improving the tank design. I intend to use the tank to dose Kalk and hope that will take care of the chemistry end of things. By the way, if anyone wants a copy of the design just let me know. Thanks in advance.
