Buying Guide
Choosing the right pool shock for your saltwater pool involves considering a few key factors. Here’s a breakdown of what to keep in mind:
- Type of Shock: Look for shocks specifically designed for saltwater pools. These are formulated to work with salt chlorine generators and won’t damage your system.
- Active Ingredient: The active ingredient is usually calcium hypochlorite or dichlor. Both are effective, but calcium hypochlorite can slightly increase calcium hardness.
- Pool Size: Consider the size of your pool. Larger pools require more shock to achieve the desired chlorine level.
- Frequency of Use: Determine how often you need to shock your pool. Routine shocking is essential, but occasional heavy shocking may be needed after heavy use or algae blooms.
- Ease of Use: Opt for shocks that are easy to measure and apply. Granular shocks tend to dissolve quickly and evenly.
- Budget: Balance cost with effectiveness. While budget options are available, investing in a higher-quality shock can save you money in the long run by preventing problems.
- Stabilizer Levels: Check your pool’s cyanuric acid (stabilizer) levels. High stabilizer levels can reduce the effectiveness of chlorine.
