Dichlor Shock or Cal Hypo Shock?

Dichlor Shock

Sodium Dichloroisocuanurate‍ is a sodium-based chlorinated granular shock that is designed to be used in a saltwater or spa environment. The sodium base allows it to dissolve quickly and clearly, leaving no turbidity or cloud to the water. Dichlor can be used in all interior types — vinyl, plaster, pebble tech, and painted finishes. Sodium Dichlor can be used as a maintenance or treatment product.‍

Dichlor, which has a pH of 6-7 at 25°C (1% solution), is typically white in color and has a slight chlorine odor. Dichlor contains approximately 10% Cyanuric Acid, so it is stable. Cyanuric Acid protects the chlorine in the product from the harmful effects of the sun's UVA and UVB rays.

To add a Dichlor shock — such as AquaClear Dichlor — to your pool or spa, simply measure out the amount needed per the volume of water and Parts Per Million (ppm) lift needed. Then sprinkle it around the perimeter of the pool or spa with the main circulation system running. (Do not pre-dilute this product before adding.)

Cal Hypo Shock

Calcium Hypochlorite‍ (Cal Hypo) is a calcium-based granular chlorinated shock that can be used as a maintenance or treatment product. Cal Hypo has the highest percentage of available chlorine and is extremely effective at eliminating algae.‍

Because Cal Hypo contains calcium, it is not recommended for use in saltwater applications, and although it does dissolve quickly, it does take longer to dissolve than Dichlor. Cal Hypo is not recommended for painted, vinyl, fiberglass and pebble tec interiors because it can possibly bleach the color of the surface. Depending on the calcium hardness and total dissolved solid levels in the water, adding Cal Hypo can cause some turbidity and clouding to the water.

Cal Hypo is white/gray in color, has a slight chlorine odor, and a a pH of 10.4-10.8 @ 77 °F (25 °C). Cal-Hypo is not stabilized as it does not contain any Cyanuric Acid (CYA).
