Algaefree 1.5kg Pool Blocks

Pool Blocks are a great way to keep your pool in top shape, this is effective for all pool surfaces. Each 1.5Kg container contains five slow-release tablets that help provide long lasting protection. The key component in Pool Blocks is a natural trace element, a copper salt that's carefully bound to last a long time. For a standard 50,000Lt pool, start by placing two blocks in the skimmer basket, and then add one block every month. This will help prevent algae from growing. This monthly maintenance style treatment ensures your pool stays clean and saves you money on chemicals. If you have a larger 75,000Lt pool, begin with three blocks and then add one every three weeks. If you have a smaller pool, you can cut the tablets in half as needed. 5 x 300g blocks.
