In The Swim Granular Chlorine Sodium Dichlor

Yes, this formula is compatible with spas and hot tubs, as well as both in-ground and above-ground pools. Its calcium-free, fast-dissolving nature makes it a versatile option for various water volumes.

While it is designed to be fast-dissolving, it is generally best practice to broadcast the granules evenly across the pool surface or dissolve them in a bucket of water first to ensure they don't settle on the pool floor, especially with vinyl liners.

The UV inhibitor prevents the sun's rays from breaking down the chlorine too quickly. This means your sanitizer remains active in the water for longer periods, reducing the frequency of re-dosing.

Yes, it is formulated for dual use. You can use it for daily maintenance to keep chlorine levels steady or in higher doses to shock the pool and clear up cloudy or contaminated water.

This product features a pH-balanced formula, which helps minimize drastic swings in your water chemistry. However, you should still test your pH and alkalinity levels regularly, as any chlorine addition can cause minor fluctuations.

Calcium-free formulas are beneficial because they prevent the buildup of scale and cloudy water that can occur with calcium-based shock treatments. This makes it an excellent choice if your local water supply is already considered 'hard.'
