Welcome to TFP!

Congrats on the new-to-be pool. Once they are within a week or so of filling the the pool, I would order one of the Recommended Test Kits. I use the TF-100 because it's the best value and they have a freshness guarantee. You can order it here: TFTestkits.net. They ship fast - you should have it in your hands in 2-3 days with normal shipping.
