Hi all... I have an easytouch automation system with intellichem. A SWCG is attached. I've been balancing my pool as replastered late last year and just got the SWCG up an running last week... I've been following the prescribed TFP chemical levels for a SWCG pool... so CYA is around 70. This is causing ORP to be funky... and my free chlorine level is now really high (13; had been 6) as presumably the system appears to be trying to get the ORP higher.
Is ORP key in that it measures the ability to oxidize... Does it trump the FC level? My target FC is 6 (is this measure affected by CYA levels?)... If FC is key I could tweak ORP to drive FC @ 6... If ORP is key, I'd need do something else... like reduce CYA to 30-40 or bypass the intellichem for the SWCG and just let the SWCG drive FC to 6 based on run time and %.
The intellichem holds the ph spot on... nice not having to monkey with that.
Any thoughts greatly appreciated!
