My CH was too high about a month ago so i backwashed to waste before a big rain and a little after to lower it. got t back around 350. now it is back to 460, and i haven't added and hardness. i did just add MA and bleach
Just finished test results
FC - 8
CC-0
PH 7.2
TC-8
TA - 45 (out of baking soda) usually stays pretty solid at 70
CH - 460
CYA - 50
Borates - 40
Any idea where it is coming from? Fill water is a Ch of 6.
Also seem to have a scaling issue maybe? PH was too high, and due to family illness i have been in and out of town alot more than expected and havent been able to keep up with it as much as i would like. Replastered march 2011. below pictures are kinda hard to see with the reflection but it looks like a grayish tone running down the sides. don't have a pic of it, but there is also large build up of white material under the rock overflow of the hottub
