I am very new to GHL and just starting to convert over to P4. I have a Stenner double peristaltic head pump that I use for daily water changes. The pump is mounted in my stand and is louder that I care to hear in my living room so I only run it at night. I have it set to run for 3 minutes per hour from 10:30 pm until 3:30 am. Is there a way for my to set up the P4 to control the pump to run between these hours and run only 3 minutes per hour?
