My fc level isn't maintaining. I shock the pool and the next day my fc level will be back at 0. I have a basic Taylor test kit which only test for fc and ph.
What you describe is perfectly normal. The chlorine could be all gone within an hour of adding it. You need to test and add chlorine as required very frequently until it holds. Check out SLAMing Your Pool to get the details.
Consider using liquid chlorine or even regular household bleach (not the scented, spashless or outside kind though) to bring your chlorine up again and again as needed. WHen you use a product called "Shock" it often is a "Stabilized" form of chlorine that also adds CYA to your water. Too much CYA causes problems and can't be removed unless you drain water off and refill with new water.
Need to know your CYA level. You need to maintain you chlorine based on your CYA level according to this, Chlorine CYA Chart. Otherwise algae will grow which will consume all your chlorine very quickly.
You have been given good advice. You need a quality test kit and the as John posted - SLAM your pool.
Liquid chlorine will correct your problems. If pool stores in your are don't sell liquid chlorine at a reasonable price then plain bleach at WalMart will do.
Good for you, and welcome to the forum. Your pool life will be way different than it ever has been. You'll actually enjoy it and not be wondering what's going on.
Ok my test kit came in & results are Fc 4
Cc 1
Cya 50
Ta 90
Ph 7.4
Recommendations? I work away from home & before I left for the week the fc was 5 came home 7 days later at 0.
Do you work away from home often? Perhaps down the road you might want to think about a salt water chlorine generator (SWG) to help keep some chlorine (but no CYA additions!) in your pool those few days you're gone.
