Keep us posted how your project is going. Go ahead and order a Taylor K-2006 or 2006C test kit (same kit but has 2-oz. bottles instead of 0.75-oz.). See the Amazon link in my signature. Only order when the seller is Amato Industries. If they aren't listed as the seller one day, wait a day or two until they restock and then order. Some of the other sellers are sending the K-2005 instead which you do NOT want.

(By the way, did you know that any time you order anything from Amazon but start with that link, the Pool Forum makes a little money? As long as you start with that link, you can navigate to any other area of their website and order anything that they have to sell and PF still makes a little money! Helps us stay online and everyone orders from Amazon at some or another, don't they?)
