Does this product affect my water chemistry?

Happy No Foam is a neutral chemical and will not affect chlorine, bromine, PH or Alkalinity level. The only slight side effect of this product is, if overused this can cause a clear jelly-like build-up on your filters as this product is silicone-based. To prevent this, use sparingly. Take a look at our Non Chlorine Shock that will oxidise any cosmetics preventing foaming.
