I just backwashed for the first time with my new filter. I let it go for probably a good 2-3 minutes after my first vacuum and then a second backwash after vacuuming again this time for a 5 min or so backwash. I did not see any circulation in the sight glass either time I backwashed. I did see some floating microbs though... but when I tried playing around with the sight glass (tightening or loosening it) water would spray out so I know the water is going through.
Am I supposed to see swirling water in the sight glass (I watched a YouTube video and his was swirling good)? Also, how long do you usually let it backwash and rinse for? Each time the pressure was at or just above 20 and then went back down to 15ish when done with the cycle. Thanks
