Opened pool up a few weeks ago and it was considerably black and is now cloudy blue or greenish. We have done many cartridge cleanings, added lots of chlorine, vacuumed all the crud from bottom. We had been using Pristine Blue for about 5 years and wanted to switch to this BBB method. (My husband was smelling like metal whenever he got out of pool.) I have read Pool School.
So, I ordered the TF-100 kit and first checked for CYA which did not even register and so assuming it is at zero. Added 3 pounds of granular CYA (as directions stated on bottle) into a sock in skimmer basket which all dissolved within a few hours.
When do I re-check the CYA level so that I can know the corresponding FC shock level?
When should I check the alkalinity?
When should I check the pH?
This is all new to me...
Can trichloroisocyanuric acid be used instead of CYA?
Is there anytime at which we should NOT be in the pool...like after adding chlorine?
Thanks for all your help.
