Have you ever had an issue with the actual mistking having issues with tap water? Or just the nozzles?I’ve always used regular tap, hard water. I have to take the front of the nozzles off and clean them with vinigar a couple times a year is all. Also, I learned in my aquarium days that if you let water sit for 24 hours it will dissipate the chlorine out and not have to use water stabilizer when doing water changes, so that’s also what I’ve always done for the chams. Fill a bucket 24 hours before maintenance, then dump that bucket into my reservoir, and use it from there.
If I had an RO system I’d go that route but I am yet to need to go that way.
