I have had a pool since 2006 in southwest Georgia. I am a believer and have used the methods described in this forum to solve any problems I have had with water chemistry balance. However, this one has got me stumped as well as many of the pool service companies in my area. I have never had such a problem as I do now.
My pool is in-ground, capacity 25000 gals, vinyl liner (replaced in 2017) with a salt water chlorination system. My present water chemistry is PH 7.6, Chlorine 21.0, Alkalinity 110, Cyanuric acid 95 and salt level 2700. Prior to my problem and just opening the pool in the spring the water chemistry was PH 7.4, Chlorine 0.0, Alkalinity 80, Cyanuric acid 80 and salt 2600. I have several river birch trees around my pool which always have produced a lot of debris plus seeds in the spring that cause me to empty the skimmer basket and polaris frequently in the spring.
The present chlorine level is high right now due to increasing dosage of bleach to get rid of what I thought was an algae problem. It has remained high because I increased the salt system to an output of 80%.
Right now my pool is green (picture attached). I looks like algae but I do not have any algae dust on the bottom of the pool when I brush it. My water feed is from a well. The pool service people think that I have a metal problem. I have added their metal out chemicals (2 quarts) and ran the pump system overnight but I do not see an improvement this morning. I do not know how to test for metals.
What I do know, is that I have had this pool since 2006, have always used my water from the same well and I have previously never had a problem that I could not fix using borax, bleach and acid. Any help would certainly be appreciated.
Sincerely, Jim Kempf
