1. What makes Pool Blocks unique compared to other algaecides? Pool Blocks are designed for long-term use with a slow-release formula, providing sustained algae protection and reducing the need for frequent maintenance.

2. Can Pool Blocks be used in saltwater pools? Yes, Pool Blocks are compatible with both saltwater and chlorine pools, making them versatile for all types of swimming pools.

3. How do Pool Blocks save chlorine? By eliminating algae, Pool Blocks allow chlorine to focus on killing bacteria. This reduces chlorine consumption and helps maintain sanitiser levels.

4. When should you put algaecide in your pool?

The best time to add algaecide is after you've balanced your pool water and completed a shock treatment. It's also ideal as a weekly preventative measure, especially during warmer months when algae is more likely to grow.

5. Will algaecide clear up a green pool?

Algaecide helps prevent and control algae, but it usually isn't enough on its own to clear up a green pool. If your pool has already turned green, it's best to shock it first, then brush, vacuum, and follow up with an algaecide treatment.

6. Does pool algaecide drop chlorine levels?

Algaecide doesn't significantly lower chlorine levels. However, when you're treating algae, chlorine gets used up faster, which might make it seem like the levels are dropping.

7. Should I put algaecide in my pool after it rains?

Yes, heavy rain can dilute your pool's chemicals and introduce organic matter that encourages algae growth. Adding algaecide after rain can help prevent an outbreak.

8. How much algaecide to put in the pool?

Always follow the dosage instructions on the product label. As a general guide, use around 250 - 500 ml per 50,000 litres of pool water for treatment, or 125 - 250 ml for weekly maintenance.

9. How to add algaecide to a pool?

Start by ensuring your pool water is properly balanced. With the pump running, pour the algaecide evenly around the edges of the pool. Allow the filtration system to circulate the water for several hours.

10. How long does algaecide take to work in a pool?

Most algaecides start working within 12 to 24 hours. You should notice algae beginning to break down or clear up within this time.

11. How long after putting algaecide in the pool can you swim?

It's generally safe to swim 15 - 30 minutes after adding algaecide, depending on the product. Always check the product label for specific directions.

12. How much algaecide to put in the pool weekly?

For regular prevention, a weekly dose of 125 - 250 ml per 50,000 litres is usually recommended. This helps stop algae from forming in the first place.

13. How long does algaecide last in a pool?

Most algaecides provide protection for around 7 days, which is why weekly application is ideal to maintain algae-free water.

14. Is it better to use shock or algaecide?

Shock is best for removing existing algae, especially in green pools. Algaecide is more suitable for preventing algae. For optimal results, use both as part of a treatment and maintenance routine.

15. Can I put shock and algaecide in at the same time?

No, it's best to avoid using them together. Shock the pool first, wait 12 - 24 hours, then add algaecide. Using both at the same time can reduce their effectiveness.

16. Do you run the pool pump when adding algaecide?

Yes, always run your pool pump for several hours after adding algaecide. This ensures the product is evenly distributed throughout the pool water.

17. Do I need to vacuum the pool after algaecide?

Yes, especially if you're treating visible algae. Once the algae starts to die off, vacuum the pool floor to remove the debris and keep the water clear.
