Hello, how can i solve this problem, I bought calcium reactor pacific sun ac2 used older model but controller v3 with wifi. I was trying to start it yesterday but i have a problem that if i open co2 at slow bubble rate and psi 20 it wont fill mixing chamber with co2 gap in 5 minutes while manual writes it must fill within 60s to reach optical sensor, than i tried to 30psi and fast bubble counter not 5 per second but really fast, and it filled in 20second optical sensor turned off solenoid but it started to open close every 10-15 seconds i think it because its not a clear gap but co2 with lots of bubbles so sensor doesnt work properly, but my pump cant reduce flow. Or what may be the reason? I put only 3.5 liters of media instead of 12liters because just wanted to try for the first time how it goes. Maybe need to add more media? Also there should be valve inside i made my own and first i eas trying with all hole open, now I half closed it still same. Please find attached video.
