Dissolving Pool Cyanuric Acid Using A Sock
SummaryCyanuric Acid for pools is sold in granulated form. It tends to dissolve very slowly, accumulating at the bottom of the pool or in filters. Instead, by placing the granulated acid in a sock in the pool strainer, it can dissolve relatively quickly and not build up in undesirable locations.
Undesirable AlternativesThe CYA package recommends either:
TechniqueInstead of those choices, the best technique is to place the acid in a sock in the strainer basket. Take a clean sock, preferably a long one, and fill it halfway with cyanuric acid. Tie the sock off. Place it in the strainer basket, preferably while the pool pump is running.
Check the sock once every 1-2 days until all acid is dissolved. Use your test kit to check if the CYA level is in your preferred range.
ResultsThis technique works very nicely. The acid is dissolved while in the sock, so it circulates nicely in the pool water. Granulated acid never leaves the sock. In the strainer basket it dissolves quickly since there is a high rate of flow over the granules.
