I am brand new to the TFP site and really excited to be here! I've read through all the Getting Started pages. Up to now I have used the traditional pool store chemicals: dichlor, trichlor, etc. We currently have cloudy water with a light green tint in the deep end. Each time I brush green particles swirl up. I also have metal stains to treat at some point. My current plan is to get the stabilizer levels down to the 30-50 range with partial refills and then SLAM if I need. After the cloudiness and algae problems are resolved then I was going to address the metal stains. Is this the best plan of attack for the current situation?
We've battled water chemistry, metal stains, and algae problems all summer. Since we purchased this home, I have been going to a big name pool store and having our water tested and just had a basic kit at home. Our pool was left uncovered over the winter and I maintained it as I could, but didn't give it the attention it needed. We went through many bouts of algae treatments and come summer we once again had a green pool, but this time it wouldn't clear up. My husband went to large home store and purchased some algaecide and we did two rounds of treatments. Out of nowhere after that metal stains appeared. A problem we haven't had up to this point. I've done two rounds of metal stain treatments, but each time chlorine levels are raised again the stains reappear. Not sure where this came from since we never had the problem prior.
As our algae problems continued, the pool store tested my water repeatedly, but couldn't find the problem. I ended up hiring a pool company and the first test they did they said our stabilizers were off the charts, in excess of 200. The first thing they had us do was drain about half of our pool and refill. After the refill they said the stabilizers were still high, in excess of 100, but that we would continue to lower it with regular backwashings. Fast-forward to now and I once again have a green pool and they told me my stabilizers are now 300. I thought we were in the process of lowering them all summer, so was a bit blind-sided that we were back where we started. I'm officially ready to manage the pool myself, but am new at it and don't want to cause further problems.
I just received my Taylor K-2006C kit and my initial CYA tests exceeded 100ppm. I've been doing partial refills on my pool all weekend, dropping it just below skimmer level and refilling. After the fourth refill I tested all of my levels (see above), this time I did a split test on the CYA with part pool water and part tap water and then doubled my figure and came out with 140ppm.
Our pool has historically held onto chlorine ever since we owned it. It has never burned off the way the pool professionals told me it should, so each time they had me shock the pool the levels would stay extremely high (10+) for weeks. I would tell them this, but they were baffled. I now wonder if we've had high stabilizer readings all along that went undetected until recently.
