Help! I'm new to pool maintenance and have been sucked in to the pool store run around. Basically our pool isnt registering chlorine. We have shocked it to death still nothing. Reading some past posts it sounds like we need to add bleach? Will order the test kit recommended from amazon tonight. The six strip results this morning were : FCC-0; ph-7.8; TA-80; TH-400; CYA-30-50. Thoughts? Thank you in advance.
