Ya....that's why I was just going to buy the cap Flow N Grow and disassemble it, and reinstall it into my reservoir. It doesn't work like Ak1's Flow N Grow titan system. it works off a timer that you can flood and drain as many times as you want in a 24hr period.
I think I can still make this work 4 me. or build one, I found all the parts that the cap uses
You can set the Titan for as many fills as often as you need.
