I have a 86,000 gal gunite pool and we have a problem with the water. The pool is located in an indoor facility down in the deep south. I've tested the chemicals and they are all within normal range. The issue is, whenever someone gets in to swim, through their movements in a crystal clear tank, they are leaving a milky trail behind them as they swim. I have also noticed by looking at an angle under the lights that it gives off these effervescent effect. While diving, some of our equipment was covered in these trillions of small bubbles. This has happened before and we don't know why?
here are the readings we just took:
Fr Cl 1.08
Tot Cl 1.75
com Cl .67
Cal Ha 490
Thinking it may have been the start of an algae bloom so we added 128 oz of Algaecide.
The weather has begun to change where daytime temps are hi 80"s to low 90"s.
If anyone has any suggestions, they would be greatly appreciated.
