I am trying to figure out how stabilizer granules that I fed into the skimmers are ending up in the pool through the returns.
Somehow it seems to be bypassing the sand filter. I followed directions and added it slowly. Any ideas?
I have a Hayward sand filter, the water has been very clear, and the pool has been open for 1 month.
I have owned the pool for 3 years, and according to the previous owner, the sand should be 5 years old now.
I would appreciate any thoughts.
