Backyard Aquaponics
A place to discuss aquaponics

I did a search and saw someone saw the 15 on 45 off timer was cheaper....anyone have a link thanks

A mechanical timer like this one is probably what they are refering to, where you can set 15 minute increments on or off.. Just set every 4th peg on for 15 on and 45 off..
