Hello everyone, first post here. We have had our pool for about a year now. The builder finished last May so he got everything in order and it as a fairly easy season for maintenance, just a lot of MA to keep pH down. I opened the pool two weeks ago, it was a little green but cleared up quickly and has stayed crystal clear. Here is what the water test looked like yesterday:
FC - 5.5
pH - <8 (added MA)
TA - 130 (bringing it down with MA)
CH - 210 (ordered, should be here this week)
CYA - ??? can't get a reading.
So last year the builder threw a bunch of CYA in the skimmer and I ordered the 20 lb. Puritech box from Amazon as it needed more, but I never threw it in the pool. Not having a full grasp on the maintenance, I figured everything was good as FC was holding in the 3-4 range but I may have had the SWG working a little more than necessary. This year I tested for CYA and it appears there is none, or it's very low. We had a ton of rain over the winter and I was draining through the skimmer what seemed like every two weeks, so I know I lost quite a bit, salt was low as well. To get CYA up, pool math says I need 13lbs to get to 70. Over the course of the past two weeks I have slowly been adding it, first 6 lbs, then 3, test again, 3 more lbs. The problem is, recent tests are showing nothing. I am using the sock in the skimmer method and it dissolves fairly quickly, and I keep the pump running overnight (except for once, oops!)
I have also read all the threads on proper testing techniques and watched all the videos. After the initial dose, the test showed between 30 and 40, so I thought I was getting somewhere. However, at some point in all the testing I had to order new reagent and I do not recall if that first test was with new reagent or left over from last year. All the tests since then (with new reagent that expires in 2020) show absolutely nothing, I can fill the tube completely and clearly see the dot, back to the sun, facing the sun, to the side, inside with artificial lighting, flash light shining through the tube... nothing.
I am thinking either the reagent is bad, or maybe the CYA as it sat in the garage all winter (unopened). Anything else it could possibly be? Is it possible it's stuck in the filter and needs more time? Maybe something in the water eating away at it? Ammonia (haven't tested for it)?
The last dose was on Wednesday and I am not adding anymore until I can pinpoint the issue. Plus, at this point I am sure I have added more than 13lbs and don't want to have to replace water. I plan to pick up new reagent at the store today and test with that. Thanks in advance and sorry for the long post!
