oh sorry I meant the JG fitting was weakening and it became brittle on me.
I like the ozone to be honest with you. I just have to remember to put carbon on both water output and air output. I sometimes I don't put anything (dangerous and risky) in the air output when I'm not home, but I have it set 50% of 50mg/h anyway (sometimes less).
IME, when ozone is on, less skimmate is there but when there are some, it seems thicker. maybe just me. but I do see the difference in clarity
I don't quite have a choice but the AC120 as far as skimmer though coz of space constraint
