Elusive timer

[Machiavelli]

I'm looking for a particular kind of timer in order to control the rate at which a pump turns on to dose limewater. I had a small black timer that plugged into the wall and 1 knob determined how long the device was off and the other knob determined how long the device stayed on.

So in this way I could set it so that it turns on the pump every minute for 20 seconds, or something equally small and frequent.

Anybody know of a timer that allows for such small intervals?

A lot of your wavemakers can do that.

I have a regular digital timer but it can only do 15 minute intervals.


As a side note, if you are wanting a very slow pump for a kalk/nilsen/ATO reactor, just get an Aqualifter pump. 3 gallons per hour is pretty slow and perfect for kalk. $15 is hard to beat, cheaper than a timer!

Thanks for the recommendation, I'll check out some wavemakers. As for the aqualifter, that is what I have right now, But the tank is a nano so I need to add limewater even slower than the pump can offer when its constantly on. This is driving me nuts because I know I had this cheap little timer that did it exactly but I cant find it anywhere.

Better off dosing Kalk via auto top off. One process covers two chores.
