Thank God they don'tJeff,
I suggest that you use what you have, but try to keep your CYA to 50 or less until you get your SWCG installed.. No rush, but you can also add the necessary salt.. Keep in mind that your pool most likely has some salt in it now, so don't add too much. If you don't have one, you will need to get a salt test kit. I recommend the Taylor K-1766.. I never trust what the cell reports as the truth, unless I can confirm it with the K-1766.
A lot of lowes and home depots have plenty of Liquid Chlorine.. Most people do not understand it is just stronger bleach.
