Timers

OMG I remember Hole in the Wall! I remember begging my Dad to drive me over to get freshwater fish when I was in elementary school.

Tony,

I am trying to make a fixed peristaltic pump into a variable pump by regulating the outflow through the use of a timer. I want to buy a fixed pump (because they are alot cheaper) with double the outflow that I need and then use the timer to achieve the proper outflow from my calcium reactor in order to regulate the alk and calcium level.
