WebAntifoam chemicals work by reducing the surface tension of the liquid films that form the bubbles within the foam, causing them to more rapidly break down and dissipate. However, there are potential adverse effects—such as toxic effects on metabolism, lowering of cell gas uptake, and reduction of yield—from the addition of antifoam chemicals. WebCheck on the balancing chemical’s container for the right quantity and then scatter the chemical over the hot tub water with the jets running. Leave the hot tub running for between 30 and 60 minutes and then re-test and adjust again if necessary. Next, test the pH level. You should have a Ph level of between 7.4 and 7.6.
