Omni pH Decreaser will slowly lower the pH level of your swimming pool if the pH gets too high. Keeping your swimming pool's pH level balanced is important for swimmer comfort and it also helps prolong the life of your swimming pools equipment. In addition, many algaecides require the pH to be balanced in order to work properly. A great feature of this product is that it is a granular chemical. This means it is safer to handle and use than liquid acids such as muriatic (hydrochloric) or sulfuric.
