We installed our 18'x38' Vinyl Lined pool late last fall so we did not get to use until this spring. I am having some problems and am seeking some of the incredible wisdom that floats around this forum. Here are the test results from this morning. BTW, I own a hardware store and have a Lamotte Waterlink Express at my disposal so that is where the test results derived from this morning:
I am working on the CYA, I know that it is low but it takes awhile to dissolve. The problem is that the SWCG is not producing enough chlorine OR something is trying to grow and the FC is dropping fast everyday. I am running my pump 24/7 and the SWCG is set at 60% right now. My salt level is 3200 ppm. I have added liquid chlorine a couple of times to boost the FC levels, but they fall back off in the subsequent days even with the SWCG running at 60-80%. I am going to test for Phosphates to make sure that is not an issue, but it is unlikely.
The water is really clear, but I just cannot figure out why the FC levels fall off. I would think that the Goldline SWCG would have enough output to maintain the FC levels daily. I also have a Coverstar Automatic Cover that is closed except for the times that we use the pool and I would have expected it to help keep some of the FC loss at a minimum as well.
I am perplexed and frustrated to say the least. Advice? Shock and hold FC levels? I have read many of the articles but I just do not know where to start. Any advice is appreciated!
Thanks for your time.
