Had a new fiberglass pool installed last year. I have the hayward sense and dispense system. Pool doesn't get used alot, but I've been running now since April and don't have any / very little combined chlorine. I haven't shocked all year - do I need to? no chloramine smells either.
Need to shock with fiberglass pool and orp controller?

Can you give us all the water chemistry. The CC is best at zero, .5 is all to common and ok and anything above 1 needs further ispection.

Jack if you're not testing with either Taylor K-2006 or TF100 you will not get advise from here. Not because we are pushing these test kits but because we don't want to offer advice on inaccurate test results that could make things worse. The 1st step to knowing how to care for your pool is getting accurate and reliable test results. Unfortunately as things stand these are the only 2 trusted test kits.
Almost guaranteed you’ll be seeing CC pretty soon if the chlorine is really that low.
would a taylor K-1004 kit suffice? I don't want to drop $210 cdn plus shipping for a test kit. I can get the K-1004 for $50 plus s&h.
No, it’s missing the FAS-DPD portion for chlorine and a CYA test. You could add a Taylor K1515 to it as get FAS-DPD.
Does ORP consider free/ combined chlorine? From what i've read, ORP is a better measure of sanitizer efficacy than free chlorine. My ORP is always above 650 so do I even need to be concerned about combined chlorine? Perhaps only when ORP cannot get above 650?
ORP isn’t very reliable especially when CYA above 30ppm is in the water. TFP doesn’t endorse its use.
