I'm fighting FC loss, then haze, then green. Rinse, lather, repeat.
Normally I maintain myself and keep it within TroubleFreePool limits. But the pool guy replaced the liner (March) and put in too much salt (4000) and bicarbonate (130) on refill. I've been letting pH creep up to 8, then adding acid (typically 24oz) to reduce pH and alkalinity together. Salt level is noticeably high (taste), but acceptable to swim in. The high salt indicator has never come on, so I've been letting salt drop with water loss/additions vs doing a 20% water change.
As I sit here staring at the cell voltage/current numbers and adding gallons of chlorine, I'm beginning to think it may be losing FC because it's "infected". But with what? The water was crystal clear and output was set at 30% w/ 12hr run time. Overnight at 100% usually nets me ~+4ppm FC. That has been my SOP for a decade. I even speculated that this cell may have lost efficiency, so 3-4 weeks ago I shocked the pool (CYA 60 - 17ppm) raised daily output to 50% (5/28). Each time the FC falls, water slowly turns milky/hazy, algae collects on the shady inclines, then it blooms green overnight.
If this isn't the cell/board, I'm at a loss. After 10 years (when I found TFP.com), I've never had a clear/clean pool that wouldn't keep FC, except when my current limiter died and when my last cell died.

Pool:
27,000 gal vinyl liner, replaced and refilled in March 2017.
Current status - light green and currently SLAMing. Raised FC to 31ppm yesterday. 17ppm today. Will re-raise to 31ppm and hold until passes OCLT
Controller:
Aquarite by Goldline,
Cell T15 was original cell type as well. Last cell life was 9 years running 12hrs @ 25% avg
Panel looks/behaves normally. Power solid, generating lit, and if activated, super is lit. All others unlit.
Current limiter replaced 4-5 years ago. Have cell current and panel behaves properly, so that does not appear to be that problem.
Average salt - 3800
Temp - 84
Cell voltage - 25.5
Cell current - 7.22
Output - 100%
Instant Salt - 3600 (Seems normal as I just added 1in of water)
Model: - AL-0
Software - R1.58
Cell - T-15
Chemistry (current):
FC - Before shock 0. Currently 17
CC - Before shock 0.5. Currently - Did not test.
PH - 7.6 before shocking.
ALK - 100
CYA - 80
CH - 130
Chemistry (target):
FC - 8 ppm
CC - 0
PH - 7.5 to 7.8
ALK - 75
CYA - 75
CH - 100-150
