Hi Digger,
You are going to be so glad that you switched off of Baquacil. Is your pool still cloudy and green. (I assume it turned all sorts of pretty shades of green as you converted from baq. to chlorine!)

Now, you just need to keep hitting it with bleach until you can get the pool to hold a chlorine reading overnight and the pool clears. You don't want to change the sand until that happens.

Go and read a lot of the posts about other people's conversion stories in the baq forum and then come back here to ask whatever questions you still have. You are really going to need a good test kit. We recommend the Taylor K-2006. A good price for it can be found at the following link. The Walmart kit you mentioned will be a temporary help but without a good kit, it will be harder for you to manage your pool and we don't want you going back to the pool store. They have enough of your money already. You'll get better advice here.

By the way -- I hope you saw my note in your top post telling you why I moved your posts into a new thread.
