here you go, you can not get any easier then this. It's called the tsunami A.T.O. (auto top off)
They work like a charm and make it so much easier to use.
I still like the plug and play items.
I bought mine from the big bidding site. The only other piece of equipment you will needs is a small pump or power head.
I use the aqua lifter pump. It plugs into the ATO. I have one hose in my fresh water reservoir ( wrapping paper Tupperware container) and the other end into the ATO.
Take and appreciate the K.I.S.S method, simplicity at its finest.
