I have a friend who came to me regarding her pool, which now has cloudy water. I went over to her place and sure enough it is cloudy. I took a sample of the water home to test it and her results are...
FC – 0
She definitely needs to shock her pool. She has been using TriChlor in the past and currently has floaters in her pool. I am getting her set up for shocking, my question is more because of her CH. She has a plaster pool and her CH is ZERO! She does not have a water softener filling her pool. Ill have her bring in a sample of fill water to work and I will test it for Calcium. Are there any other reasons why she would not have CH in her pool? She definitely needs to add some. What is the cheapest source and any special considerations we need to think about when adding it to the pool?
