So I just restored an older hot tub. I cleaned it 4 times with AhhSome. The first 3 times I had brown junk in the foam. The last time, i had nice white foam. So I assume its clean.
After the 4th cleaning, the next fill I just couldn't get pH under control. It was always above 8. 2 oz of acid did nothing for it. So I dumped 4 oz of acid in and overshot it. It was way below 6 on the test and smelled of acid. So to be safe, i decided to drain and refill. So now everything is doing fine except for the FC and CC. Fresh fill, CYA of 30, FC of 5 or 6 and it drops to zero overnight. So I thought I needed to SLAM it. So i brought FC up around 12 for the past 3 days. CC has been in the 2.5 - 3 range the whole time. Its a fresh fill in a clean tub and i have a CC of 3??? Makes no sense to me. I've been holding at 12 for 3 days now and nothing is happening. So last night i put another 3 oz in to bring it up around 15 or so. I didn't get a chance to test it this morning.
Any ideas what i'm doing wrong??? Seems like I'm missing something. There is no way i should have a CC reading of 3 on a fresh fill in a clean tub.
