We are completely new to pools and are desperate for help. I've been searching through countless forums, but I cannot find a post that matches our issue with instructions on how to fix.
We have a Coleman 18x48 above ground power steel pool with a cartridge filter. It holds 6,000 gallons of water. We use HTH 6-way test strips to check water levels. We have been running the filter nearly 24x7, skim the top and clean the filter daily and have vacuumed a couple of times. We've only been able to swim in it a handful of times because of the imbalanced water. The pool is in full sun for the majority of the day.
When we shocked the pool for the first time, it turned brown. We made the mistake of shocking it before going away for a weekend and shutting off the filter. We've cleared that up, but the water is just starting to turn cloudy and we cannot get the chemicals to the correct levels. Over the course of the last 4 weeks, we've added cyanuric acid, baking soda and algaecide and consistently keep chlorine tablets in a floating unit.
We just shocked the pool 2 days ago. Here are our current readings:
FC = 0
PH = 8.4
TA = 240
TH = 200
CYA = 100
Please advise what we need to do (and in what order) to stabilize the chlorine and bring the PH and TA down to acceptable levels.
Many thanks in advance,
