I've got my work cut out for me. My mother-in-law's pool is around 15K gallon, 45 years old, plaster, with slippery green steps and ledge. Her pool guy hasn't shown up for a month and won't return calls or texts. 40 degree weather (105 F) so guess who?!?
She's pretty stressed (mid 80s) so we had a cuppa and she told me about the pool. She puts $50 in a puck container and the pool guy comes every few weeks and brushes the pool and backwashes the filter. He fills the floater with around 2 or 3 lbs of trichlor pucks and leaves her another 2 or 3 lbs to put in later. Long story short: 180 ppm CYA and I've drained/refilled 10% twice (just down to plaster because it's so hot). I'm hoping for a cloudy day to do a couple or three more deeper drains, then SLAM.
My question is about the stains. Trichlor doesn't change them nor does vitamin C, so maybe copper from cheap algaecides? It seems somewhat likely given the history. If I'm going to do all this draining, why not chelate the metals, if they exist, before draining? Are there downsides arising from using the sequestrant? With Christmas coming and this pool being across town, I don't have much time to get the pool in shape for a favourite swimming time.
Thanks so much for any/all thoughts on this!
