I wonder if someone can clarify the statement made in "ABCs of Pool Water Chemistry" under The Pool School that "Solid stabilizer can take up to a week to fully register on the test, so don't retest your CYA level for a week after adding some." Does that mean that the stabilizer is not available (or slowly becomes available) during the first week, or only that the standard test does not detect it? In particular, does that mean that any liquid chlorine added during the first week after a refill will get decimated by the sun?
As a related question, what about the stabilizer that is released by chlorine tablets (trichlor) and chlorine granules (dichlor)? Are these forms of CYA available and/or register on the test sooner?
