How can I create an extremely slow drip, like only 5 gallons per day?
I want to do a continuous water change system on a 40 breeder. I'd use a 0.5GPH drip irrigation emitter for 12g/day on a 100g tank; but I need less than half of that, and they don't make drip emitters that slow.
It has to be nearly maintenance free and reliable. I don't want to worry about a flood if I go on vacation for a week. I guess maybe a needle valve might do it?
