The test kit that we recommend is the K-2006 or K-2006C (same kit, larger reagent sizes) that can be found in the Amazon link in my sig. Only buy that one if Amato Industries is the seller, because some of the other sellers are subbing a different kit. If you'll get your kit, test your fill water and post results here, we can tell you what/how much to add.

Welcome to the forum and congrats on the new pool!
