## Product: Clorox Pool&Spa Shock XTRABLUE
**Brand:** CLOROX POOL & Spa

## Pros
- Comes in easy-to-use 1-pound packages and dissolves easily in water.
- Effective for maintaining blue water throughout a hot summer.
- Recommended for use with well water containing sulfur and iron without issues.
- Works well with a floating chlorinator and 6 in 1 chlorine tabs, without over-chlorinating.
- One package effectively treats a 12,000-gallon pool, covering more gallons than many other products.
- Successfully changed black pool water to blue after using 4 packs in a 10,000-gallon pool.

## Cons
- Causes water to turn green and ineffective against algae growth after multiple uses.
- Initial chlorine levels were weak, with no improvement even after additional applications.
- Potential safety concerns with storing granules near other items.
- Noticeable delay in pool entry safety, contradicting the advertised 15-minute claim.
- New formula sinks instead of dissolving quickly, inferior to the previous version.

## Bottom Line

While the Clorox® Pool&Spa™ Shock XTRABLUE®2 offers convenience and some effectiveness in maintaining pool clarity, its inconsistent performance and potential issues with algae make it a mixed bag. If you experienced water turning green or it being ineffective, you might want to consider exploring alternative brands or sticking to the original formula. For those in need of a larger coverage area or dealing with specific water conditions, it might still be worthwhile. However, some users expressed greater satisfaction with other brands, so consider your options if the results don't meet your expectations.
