So i am going to start using Kalk in conjunction with ESV 2 part. I will only be using it at night to keep my PH more stable. I have a swing from 8.2 to 7.9 at night. My question is. I have it hooked up to my APEX and it isnt online yet but i have the stirrer set to only activate for 5 min every hour. Do i or should i have the stirrer always on or just start up int every hour to keep the KALK stirred up. I dont know how long the motor will work if it is on 24/7 to only be used 12/7. Thanks for any help.
