I have not received my P234 test yet but have a 5-way test kit from Walmart. I plan on filling my new A/G pool (8,600 gals) with softened well water. Would it be prudent to test my water from the faucet and post those numbers so I can get an idea how much bleach to purchase? I am wondering how much CYA (already purchased) to add also. Thanks for your replys.
