Guest Rick Posted September 24, 2005 Report Share Posted September 24, 2005 I have a 15x30 freeform inground pool and it's 3 ft. at one end and 6ft. at the other. We run a saltwater chlorineter and cannot get a read on free clorine. The ph is 7.6 and stays there for 7-10 days then rises slightly so I add a little muratic acid and its good for another 7 - 10 days. The chlorine reads around 2.0 - 3.8 but when I do a complet test for free chlorine (tc - cc = fc) included in my test kit I get ZERO. I get a green tint of algae every now and then but it goes away if I turn the chlorinater up to the max. But then the tc goes way up above 6.0. I have a little issue with pool water burning swimmers eyes, just slightly. Do I need to shock the pool and if so can just tern the chlorinater up to the max and let the chlorine get to the level I need to shock the pool? the chloriater manufacturer told me I would not need to shock he pool so I don't know how they expect me to burn off the combined chlorine?

Guest Sally Posted September 24, 2005 Report Share Posted September 24, 2005 Shock with either dicloro or non-chlorine shock (O2). You need to burn out the chloramines (the dirty, used-up chlorine). Quote Link to comment Share on other sites More sharing options...
Guest Guest_Mike_* Posted September 24, 2005 Report Share Posted September 24, 2005 Try setting your salt generator at a consistent level (maybe 40-60% depending on water temp and sun exposure) and keeping a good level of NaCl (2800-3200 ppm) while constantly watching ph and TA. Does your pool have an over-flow grate in the tile line, if so then you can always add water to reduce chlorine. Quote Link to comment Share on other sites More sharing options...
Guest Nickel2mom Posted September 24, 2005 Report Share Posted September 24, 2005 I have the same situation as the previous post. Will shocking with a non-clorine product 'free' up the free clorine? It was all so easy last year when it was a new pool... Quote Link to comment Share on other sites More sharing options...
Guest Lars Svendsen Posted September 24, 2005 Report Share Posted September 24, 2005 Are you giving away free Clorine, cause my above-ground pool is still very green for July and the liquid shock isnt working. Quote Link to comment Share on other sites More sharing options...
