I am over in Spain and I am interested in the fact that you are not getting a reading as it would appear that I am not either. What I would like to know is when you do the test for chlorine what colour does your water go when you put the drops in your test kit. The reason me asking is my water does not go the yellowish colour to get a reading , mine goes like and orangy colour this is what I can describe the colour as. And its driving me crazy. I have shocked my pool done a test and nothing still the same orangy colour. So if you can help in any way or anyone else who reads this I would greatly appreciate anyones help on the matter
It seems that I am still struggling with this problem; I opened up the pool this spring; it was slightly greenish and slightly cloudy; used a Trichlor shock product twice, and the pool cleared up pretty quickly (3-4 days); however, once again I am getting no free chlorine. Pool store tested (using a photometric reader, though I don't know the test they use (it IS a drop test, though), and I came up with ph 7.2, total alk 100, cya 0, free chlorine 0, phosphates 0. How is it I am getting a CYA of zero if I shocked with trichlor and have been using 3" trichlor tabs in my chlorinator? Can the chlorine bleach out the CYA test? I will get the ammonia test; I should have done that last year but did not. Do I correctly understand that I can use regular liquid bleach (if it is unscented) to shock (especially in this case, if I need to add a tremendous amount)? I am nearly at my wits end; the pool looks beautiful, but I get no chlorine reading, even though I smell chlorine when I open the pool. Ugh!
Thank you for all your help; I wish I had followed through on everything last year.
