With the summer coming and the fact we are taking our honeymoon in October we were thinking about adding an ATO unit to our 30 g tank. The tank has a 250w MH pendant and an open top so evaporation has been a problem. Also, if we add a fan I know this will add to evaporation. I have been looking into ATO units and I would like to buy an all in one system. We are both terrible with any sort of building/engineering and know nothing about pumps, tubing, drilling, or anything of that sort. We are basically the anti-DIY reefers because we know we would come home to a flood/fire. So what is the best all in one system out there?
