I think you forgot to put your testing results.

What kind of drops kit?

By the way, pool stores are notorious for giving inaccurate testing results. You are better off doing it yourself. The kit we recommend is the Taylor K2006 or 2006C (better buy). Can't buy it locally but you can get it through this link:> http://pool9.net/tk/

If you use those tabs, you have to be able to monitor your CYA levels or you can get into algae trouble. The higher your CYA goes, the higher the chlorine level must be. More about the CYA/Chlorine connection here:> http://pool9.net/cl-cya/
