I have been using the pool calculator for years and it has keep my pool looking great, I recently switched to SWG and love it! I have some questions about my results and I'm wondering if anyone can help.
Can you help me understand my results:
22500 gallon plaster salt water pool salt 3900
Free chlorine 6.6
combined chlorine 0(sample remains clear after adding 5 drops of R-0003) of taylor fas dpd kit
cyanuric acid greater than 100
pool is crystal clear and feels and looks great
I would think with a Cyan Acid of >100 and Free chlorine of 6.6 that I would have some combined chlorine.
is the Calcium hardness throwing off my calculations? I have repeated this and get the same results consistently
