I tested my cya and it is at 30. I would like to raise it to either 50 or 60. using the pool calculator it tells you for 50 add either 80 0z by weight or 83 oz by volume and for 60 either 120 oz by weight or 125 oz by volume.. I have a 30000 gallon pool. A few questions. I bought a 4 lb container from walmart of stabilizer conditioner. ingredients were 96 % cya 4 % other. So I guess thats good. First am I to take it that that whole container would be considered 64 oz by volume. I am getting confused by the (by weight or by volume) and I was told to only add it 1 to 2 pounds at a time and run filter 6 hours before adding another 1 to 2 pounds then 6 hours and then add another 1 - 2 pounds. Is this correct. The HTH rep said it is slow dissolving. ALso after adding it how long do the kids have to wait to swim in the pool safely. Next After the full amount is added, is it correct that i should wait a full week before tested the cya level again to make sure it has all dissolved. I run my filter about 7 hours a day. where my numbers work well with that amount of time. my cl is at 1-2 and my ph is 7.6 my ta is 70 my ch is 130 and my salt, is up to 2700, i need to add another 80 pounds to bring it up to about 3000. Please let me know thanlks
