The water chemicals are not correctly balanced;
1. The chlorine is extremely high. It is not safe to use the pool currently. The chlorine MUST be lowered to use this pool, also to have the chlorine this high will and is currently damaging the already aging pool heater. The internal heating core is designed to not exceed 5-10 ppm of chlorine for no more than 24 hours, it is currently at 5 times that level. It can also damage the pump seals on all pumps.
2. The Cynuric level is very high about 5 times too high also. This needs to be between 30-50 ppm, its currently sitting between 120-150. The only way to lower this is to drain or 1/2 drain the body of water.
3. Alklinity and PH are showing in opposite directions meaning they have been balanced seperatly, prolonged exposure to this type of imbalance will greatly reduce the life of the plaster, this should be balanced ASAP.
I also feel that due to organic growth outbreaks in the swimming pool ma have caused the maintenance provider to over chlorinate. Instead of simply removing the phosphates and then shocking / maintaining a mildly high chlorine (5-10 ppm) level this pool is now in a dangerous condition.
All water issues can be resolved by removing phosphates (algae food), chlorinating properly 5-10ppm, and keeping the ph in line, as well as now draining 50-70% of this pool to bring it back in line. This all can be achieved for approx $250-400 service charge.
