Pool Math tells me that my FC should be a minimum of 4 with a Daily Goal between 9 and 11 yet the suggest level listed elsewhere on TFP say much lower.. like 3-5. Why is this? What should my FC level actually be?
What's your CYA reading?Pool Math tells me that my FC should be a minimum of 4 with a Daily Goal between 9 and 11 yet the suggest level listed elsewhere on TFP say much lower.. like 3-5. Why is this? What should my FC level actually be?
Minimum and target FC are different for SWCG versus non-SWCG. I think that's where you are seeing the differences. Refer to the Chlorine / CYA Chart that Divine Dave linked to in post #2
If your SWCG is operational and you are actively using it to chlorinate the pool use the SWG Pools section of the chart. If manually chlorinating the pool use the Non - SWG Pools section of the chart.
CYA is the most subjective test you'll do and it is frustrating. After you do a lot of them you'll feel better but never will you be happy. Just make sure you keep the FC where the Pool Math indicates for your "estimated" level.
Could always buy one of these if you're really bothered by the test so much - Cyanuric Acid Portable Photometer - HI96722 - Hanna Instruments
