Small increment timers

[chris stevens]

Does anyone make a timer that works in small increments, like a minute or so? I want to create an auto top off system using a powerhead and some tubing connected to a timer that will run it for like a minute once a day.

Dunno, but have you thought about a float for your top off instead of a timer?

try a digital timer for house lighting. i think they can be set by the minute.

You would have to have a pretty low flowing ph of <60 gph or use a ball valve to control flow even for just 1 minute. If your dead set on doing it this way I’d use the Timex Electronic Seven Day Timer which can be set in 1 minute increments.

Still, I agree with austinsdad about getting a float for ease and less hassle.
This one from premiumaquatics.com is only $60

can this be used in the main tank though? i don't have a sump. i was thinking about the timer method because it seems less obtrusive

You should be able to adjust the “float switch” higher from where it suctions so you could use it in the main tank as well. Also I found 3 other suppliers of for this switch.
