I saw one similar as both of those commercially for sale this last week.Dual floats and you supply the ph and replenisher box.Looks like a simple sound invention to me, and I think I'll probably be using this type of set up on my nano first then my display.I personally have liked the rythm of topping off a tank, but two?Naaahh!!!Thanks for the help.I think I'll start stocking the tank around my birthday.
