  1. The ph seems to have gone down to the 7.8 range however i am still showing a high fc rate (the strips i use only go up to 10ppm) i was supprised to see the combined level of chlorine on the strip was showing in the 8 range. why would that be if there is still so much fc? Regarding the liquidator can it be used with the nature 2? lats year when i used the nature 2, I kept the pool at 1ppm thru the summer and shocked it with liquid chlorine once every two weeks. do you think using the liquidator i will not need to shock any more? with the nature 2 what would be the ideal level of cya?
  2. Richard Its very sunny outside today in jersey so hopefully the Fc will burn off, I tested the water for ammonia this morning and its totaly clear..i am still getting a very high FC and PH level and i presume there is nothing to do but wait it out untill it all burns off. do you think that the high ph for the next few days can damage the plaster finish? I use a nature 2 cartridge during the pool season to have low chlorine in the water. (i havent installed it yet becouse my water was not balanced). what is your feeling about the product? is it safe to keep the fc at 1% as they suggest? 26 gallons of 12.5% chlorinating liquid in 48,000 gallons would raise the FC by 67.7 ppm which is very high (yes, you added too much -- the 10 ppm FC at a time would have been better). You are lucky your pool didn't get cloudy and/or produce scale since the pH would have shot way up to around 8.6 from the chlorine and the saturation index would have been over +0.9. However, within the hour, the chlorine would have oxidized the ammonia and brought back down the pH a little. If I assume that the 4 ppm ammonia-nitrogen was correct and that this consumed about 30 ppm FC, then the pH would have dropped to around 8.4 and you'd have about 38 ppm FC left over and the saturation index would be +0.8. Still pretty high. So yes, let the sun burn that off, which it should do somewhat quickly since the CYA level isn't really high. You might have the FC drop by a third in one day -- maybe almost half if you are in a very intense sunny area (though we're not in June yet). The pH will drop as the chlorine gets broken down from the sun and should get back to around 7.5 to 7.8 depending on what FC level you let it get to. In the future, use The Pool Calculator to figure out the dosing of chemicals for your pool. Richard
  3. decided to go with the chlorine... added 26 gal of liquid chlorine 12.5% and its showing a very high FC after four hours )))(starting to wonder if i added to much:) ) i will leave the pool open to the sun for the next few days untill it all burns off. Richard thank for all your help..you were on the money..
  4. i retested the water at the pool place and got this reading. FC 0.0 CC 0.7 ph 7.3 ch 240 ak 80 cya 15 phosphate 1000 ? they gave me some chem to kill the phosphate and said thats whats eating the fc and cc. i found a test kit for ammonia at a pet store and tested the water it showed a reading of 4ppm. what should i do?
  5. Richard, The pool water was clear when i opened it after the winter and it is still clear.i am not sure what the reading on the cya was before it was closed for the winter .What is the typical amount of amonia (ppm) that should be in the pool? i will see if a local pool store can test for it. The only way to get rid of the amonia is to drown it in chlorine? Should i first worry about the cc before trying to get the hardness and the cya into acceptable ranges? The pool size is a 23x50 3 1/2 TO 8 1/2 deep. Wht type of chlorine would you use for such a situation?
  6. Richard, Thank You for you help ! I tested the chlorine with the two gallons and i got a high reading which tells us that th chlorine is good. i had just opened the pool after the winter and it was covered with a hard canvas cover. i took the water on friday to a pool store to get it tested and here are the results. fc 0.2ppm tc 2.1 ppm cc 1.9 ppm ph 7.5 hardness 90 ppm alkalinity 80 ppm ca 10 ppm copper 0.07 after receiving these results i added 25 lb of hardness and 4 lb of ca. any suggestions ?
  7. have a 48000 gal gunite pool and added 6 gallons of namco (blue shield ) liquid shock treatment whick has 12.5% sodium hypochlorite per gallon. An hour later i got a 0 reading of free chlorine. It seem as if this product had no effect on my pool? this is the second time i have tried this season. All other indicators seem to be ok (i tested the strips on the spa and they showed a chlorine reading I use a powder form of chlorine for the spa). the only issue that i had when opening the pool was a high ph level i used muric acid to bring it down. Is the problem with the product or my pool?
