Hi all, newbie nobody here from Houston. I just had a 13,700 gal IG plaster pool/spa put in by A&S. I'm a very hands on type of guy and have dove right in learning about water chemistry and such. While it all makes pretty good sense to me, I am confused about the FC level. So A&S put in the Nature2 deal with the cartridge and puck feeder and tells me that for warranty purposes I have to keep the chlorine at .5-1 FC as the cartridge does it's magic. After reading on here for the past month that seems to not to be an OK FC count (not to mention the pucks add CYA). Now, my FC has gotten away from me. for the first week or so it was about 1.0. Pool School start up guy told me to "go ahead and shock the pool once a week" and gave me several 1lb bags of that ReFresh plus. So, because I'm new and "trusted" Pool School guy I do exactly that and throw a bag of that in once a week (3 bags over the past 4 weeks). I bought the K-2006 test kit and have been testing everyday and my FC is at 9.4. It seems to stay at 7-9+ no matter what. So I turned the dial down to 1 on the Nature2 to see if that helps and it didn't. So I took out all the Tri-chlor pucks from it today so that it's not introducing any new chlorine into pool and to allow the FC to come down. Can that bag of ReFresh keep the FC high for all week since i put the last one in 3 days ago? I understood that those shock bags were like a 24 hour deal at best?
After reading about all the shocking and Nature2 and such I'm interested in following the TFP way. Pool water is crystal clear and here are the #'s:
Pump runs 8 hours a day.
FC 9.4
CC 0
PH 7.4
TA 120
CH 300
CYA 30
Also, all of the literature that A&S gave me says DO NOT enter pool at FC levels above 3.0! But reading here, that doesn't seem to be the case. So at what FC level is it unsafe to get in the water?
Thanks for all the help. I hope my post made sense.
