Ok Im a newbie and started on this site last year when I got my pool. Got the TF-100 kit and all has been great with my pool since doing the BBB. The neighbors however not so good. He is a pool guy who loves to go to the pool store and buy all the pre-packaged stuff. Shocks, stabilizers, clarifiers, you name it. So lately I have told him about this stuff here (BBB) getting him to change. Ran tests the other day and his chlorine is at 0. He uses all the time Trichlor pucks. Tested his CYA and I get roughly 80. His PH is about 6.8. I have never dealt with stuff so out of whack. I put in yesterday 3-BIG jugs of Bleach to no avail. Chlorine still does not register. Using the k-1000 kit.
After reading here I told him he might need to drain down a foot and then go to shock levels with bleach. Maybe an Algae bloom?? Heck really do not know. I told him to go to the pool store and buy straight chlorine (5gal jugs) buying 3 of them. Chlorine is 10.8%. thought this would be more efficient than a pile of clorox jugs to try to correct. His pool is roughly 29,000 gal. Told him to store away the pucks for now. Have no idea (being a newbie) if I should even get involved in trying to help/convert him. Am I doing this right, is my thinking right? What do I do...HELP!!
