I finished filling the pool and spa on Saturday. I couldn't resist the urge to break out my TF-100 and do a test on the fill water. The pb is coming tomorrow to do the initial chemical startup. My question is how long should I wait to retest after he puts in the chemicals? Here are my test results below** The TA seems way off base so I don't really trust that.
