We recently bought a house with a pool and the kiddies are all over me to get it open. All of the levels were okay with the exception of the chlorine levels which were so high they were bleaching out the tests (both my kit and the store's). The pool has been covered all winter with the pump running about 3 hours each night. For about a week we lept the pool uncovered during the day so the sun would hit it, but no change in the chlorine levels. The store that did the testing thought the level was up over 10ppm, so I added enough sodium thiosulfate to lower the chlorine level by 10ppm. However, now I am showing a chlorine level of 0 and I'm sweating because I think the pool store gave me bad info and I should have added the chlorine neutralizer in small amounts rather than all at once; I may have added too much of the neutralizer and I may be into negative chlorine numbers. Here's where we are now:
Size: 40,000 gals
type: plaster
FC=0
TA=80
PH=7.2
CYA=60
I also have an inline chlorinator that is set to 'full' and has chlorine tabs in it.
I had seen some references to bucket tests that others had used to gauge how much chlorine they would need and am wondering if there is a similar test I can do before I start putting granular chlorine in the pool...
Anyone have any suggestions?
