## Product: Clorox Pool Shock Plus
**Brand:** Clorox Pool & Spa

## Pros
- Effective in killing algae, especially for non-circulating pools.
- Maintained pool clarity and cleanliness for several days.
- Suitable for pools where the pump cannot be run consistently.
- Reasonably affordable price point for a pool shock product.
- Successfully clears green and cloudy water, achieving sparkling clarity.
- Transition from Leslie's products to Clorox was smooth and without issues.
- Maintains water clarity for extended periods (3-4 weeks) without additional treatments.

## Cons
- Not safe for vinyl pools as advertised; can bleach liners.
- Slow to take effect, requiring a couple of days for noticeable results.
- Less effective compared to traditional chlorine shock products.
- Requires more applications and effort (e.g., multiple brushings) for algae removal compared to other products like Calcium Hypochlorite.
- Initial application can be tricky, leading to performance issues if not applied correctly.
- Some users report the need for combining with additional products for optimal results.

## Bottom Line

Clorox Pool and Spa Shock Plus, 1 lb is a solid choice for pool maintenance, especially if you want an affordable solution that can effectively kill algae in non-circulating pools. However, it may not be the best option for vinyl pools due to potential bleaching issues. Despite its slower action compared to traditional chlorine shock products, it eventually provides good results if used properly. For those seeking quicker and more effortless algae removal, a Calcium Hypochlorite product might be a better alternative.
