Hello!
I joined this group about a week or so ago and have been reading many past post so I don't repeat too many questions. I have the Taylor 2006 DPD testing kit and discovered several things:
- that I was using the wrong end of the scooper for the powder (so add me to the statistic as well)
- that my CYA is extremely high and have to change out my water
- that I am not very good at math or chemistry and struggling a little with the pool math app (I'll figure it out eventually - just a little slow)
My test results are: (tested at 5pm 5/9/2020)
FC: 7.0 (I added about 64oz liquid chlorine at 8am after I had a FC reading of 1.5)
CC: 0
PH: 7.6 (not sure accurate after adding LC)
TA: 175
CH: 925
CYA: 100+
My water is crystal clear and I can see all the way to the bottom. I don't see signs of green or algae. I have pebble tec. The pool is 80 degrees. I've skimmed out all the sheddings from the trees, brushed and vacuumed. I seem to be skimming the pool at least 3-4 times a day.
Before I took over managing my pool (and we'll see how it goes) the companies I had caring for my pool never told me that my CYA was high. They were using the "pucks" and have been for at least the 2 years we have been here. Why wouldn't they tell me that these were high and I needed to change my water?
Reading past posts and the SLAM - seems like I am going to need a very high chlorine level to offset the high CYA before I can get the water changed. I live in Tucson, and not ever having done this am going to need some help and have to figure out who can help me and how to drain my pool. With it being extremely hot already, I would like to talk to the water company to make sure it is not going to cost a fortune to refill the pool.
Short of changing the water...in the meantime....what do I need to do to make it safe for swimming? If I understand correctly CYA is acid, so we would basically be swimming in an acid bath? I greatly appreciate your knowledge and assistance.
Thank you, Shannon
