Oh, No!

I believe you got "Pool-Stored". 9 lbs of Alk Up in your little tiny pool????? How much did they ream you for it? Did they bother to tell that it's EXACTLY the same chemical as ordinary baking soda (Arm&Hammer) you buy at Shop-Rite?

Please post the numbers they gave you--the important ones are:
FC (free chlorine, the good stuff--probably 0)
CC (Combined Chloramines--used up chlorine, could be anything)
TC (Total Chlorine--should be FC + CC)
pH (how acidic or alkaline your water is)
Total Alkalinity or Alkalinity (this is a buffer for the pH).
CYA: (Stabilizer or Cyanuric Acid--slows chorine breakdown--You need some, but not too much)
CH: (Calcium Hardness, or Calcium or Hardness--do NOT let them talk you into buying calcium--you do not need it NO MATTER WHAT THEY SAY!)

They like other numbers, like Total Dissolved Solids--generally useless, Acid Demand, Base Demand (both useless as well).

You should get a "leaf rake" and get out those leaves with it to save your filter. It goes in a standard skimmer handle and look like a butterfly net with a squeegee at the end.

Then we can advise you. You'll be happy to know you can use bleach instead of "shock" and it will work just as well. Actually--better than "shock". Actually, there's no such thing as "shock"--"shock" is a verb, not a noun, but they use it to describe all sorts of chemicals. Double strength bleach is sold by pool stores as "Liquid Shock". One gallon of that is exactly the same as 2 gallons of Ultra Bleach.
