More about this product
Algaefree 1 5kg Pool Blocks are designed to effectively eliminate algae from swimming pools, ensuring clean and clear water throughout the year.
Algaefree 1 5kg Pool Blocks provide a reliable solution for controlling algae growth in swimming pools. Each container contains five slow-release tablets, each weighing 300g, that are effective for all pool surfaces. The key ingredient, a copper salt, is carefully formulated to offer long-lasting protection against blackspot, mustard, and green algae. For optimal results, place two blocks in the skimmer basket for a standard 50,000Lt pool, adding one block monthly. Larger pools may require three blocks initially, with subsequent additions every three weeks. Smaller pools can use half tablets as needed, making this a versatile maintenance option that reduces chlorine consumption and chemical costs.

Great value for money
Spent a while looking for the right Algaefree 1.5kg and this kept coming up as the best value. I can see why — quality is impressive for the price. Delivery took just 2 days to Townsville which is great. Packaging was solid and everything intact. My partner and I both use it daily now. Highly recommended.

Outstanding value
Bought this on a bit of an impulse after seeing it on the site and really glad I did. Quality is much better than the price suggests — feels premium and well made. Ordered Monday and it arrived Wednesday in Sydney. Nothing loose or damaged. A few people have asked where I got it.
