Hello everyone, I'm so glad I found this forum. I am running in to significant chlorinating problems this year. After purchasing and adding 40lbs of Cal-Hypo 53% over the course of this season and seeing no results, I have finally given up on my local pool store and am ready to take control of the situation myself.
First the specifics on my pool. I have a 32' x 16' in ground pool with a vinyl liner that was replaced two seasons ago. I am running a sand filter with a 1hp pump. I have had the pool for 8 seasons and aside from a few trouble spots I have usually been able to clear it up relatively quickly and keep it clear most of the time (some seasons are easier than others). This season has been the hardest ever, I have now gone 6 weeks without being able to get the pool anywhere near a usable level and my six year old daughter is threatening to disown me. :) At last testing my water was:
FC 0.6
CC 0.6
PH 7.4
TA 140
Now my problem. My pool water has been green and filled with a significant amount of algae since I opened it (which was a late opening due to a broken pump). At the suggestion of my pool company I made the mistake of using a sodium bromide algaeicide and now I am not able to get my FC up to a level high enough to shock the water and kill the algae.
Before I found this forum and realized what havoc sodium bromide can cause to my FC I thought I may have had a chlorine demand problem, so I got a K2006 test kit and performed a bucket test for chlorine demand. I was able to get the FC in my bucket to 12.0 with 4 tsp of bleach and it has held at 12.0 for 24 hours with a CC of 1.5. In fact, it never decreased over the several hours I was adding bleach to the bucket. At this point I'm wondering if my problem has more to do with the sodium bromide than a chlorine demand problem.
I have bleach on hand and am ready to start adding it to the pool in 40ppm doses to reach the requisite 80ppm to overcome a potential chlorine demand but am unsure if that's the right route to take.
Any help would be greatly appreciated.
