New pool owner here and still trying to learn about pool chemistry. We bought a house with a 25k gallon in ground vinyl pool that is approximately 20 years old. We suspect the pool was unused for the last 10-12 years (pool store had records that the liner was replaced in 2012) but was covered during the house sale. After uncovering, we scooped out most of the large debris but could not see the bottom of the pool due to all the algae.
We hired a reputable pool company to do a “green to clean” and they treated for phosphates and shocked it, but the water remained very cloudy. After a few visits without any change, we got impatient and took a water sample to the pool store. They set us up with alkalinity booster, algaecide, and enough granular chlorine to shock for 3 days. After that we went rouge and added flocculant without testing water chemistry (I know…). Once the pool company finally got back with us, we fessed up and they’ve been trying to treat it for the last month.
Since then, the sand filter was replaced with cartridge, more chlorine, constant running the pump, clarifier, more flocculant, muratic acid, phosphate remover, etc, etc, and we are still not making progress with the cloudiness. The progress photo attached was from a couple weeks ago.
The last visit was over a week ago when the pool guy got FC to 10, but now the water has changed from cloudy white to a blue-green. Two days ago I tested for chlorine and FC was at 0 and CC at 2.
I’m at a loss of what to do and where to go from here, especially with two 32 oz bottles of flocculant in a 25,000 pool. The pool company is either dragging their feet and/or confused about what to do, but they told us it is risky to drain because of the age of the liner.
I have the Taylor K2005 test kit, but I need help with what tests I should do to try to tackle this pool. What tests should I do and what should I be monitoring first?
