Well, the builder has turned it over to us now and they are working on a few final punch list items. They gave me the proper set points for my pool (don't have those with me right now) and advised I buy a better kit than what they give us. I am pretty sure they use the TF100 or the K2006. Their cost is 97.00....and I know I can get it here for much less. Anyway, we have a Saltwater pool. Which kit is best for me to get and do I need to get any other test items (strips etc) to go with my kit?
