Know before you buy
This product uses Sodium Bisulfate as its active ingredient. It is a highly effective, dry acid compound designed to safely lower the pH levels in your pool or spa water.
Yes, Nu-Clo PH Minus is formulated to be safe and effective for both swimming pools and spas. Always ensure you follow the dosage instructions specific to your water volume.
This is a fast-acting, high-strength granular formula designed for quick results. While the exact time depends on your pool's total alkalinity and volume, you should see a shift in your readings shortly after proper circulation.
To ensure even distribution, it is best to dissolve the required amount in a bucket of pool water before pouring it around the perimeter of the pool. Avoid adding the dry granules directly to the skimmer, as this can cause concentrated acidity in your plumbing.
Yes, because pH and total alkalinity are closely linked, lowering your pH will also have a slight impact on your total alkalinity. It is recommended to test your water chemistry after treatment to ensure both levels remain within the ideal range.
