Free, Combined and Total Chlorine

[@thecinephilefish9465]

Thanks for the explanation. I’m a lifeguard and somehow my free chlorine reading is always higher than my total chlorine reading. That doesn’t make much sense to me. Is there anything I can do?

[@ithirstyforknowledge]

Very well explained. Thanks

Hello sir can you please clear this up for me so this is exactly how I test my pool with a photometer so if my free chlorine is greater than my total chlorine then this means I have No chloramines correct???

Free chlorine is a component of total chlorine so shouldn't be showing up as higher than total chlorine.
