Product Description
Directions:
- Ensure chlorine and pH levels are correct.
- Remove gel block from plastic cup and place it into the skimmer basket.
- 24 hours after installing gel block backwash filter twice (or clean cartridge filters). This is important as more dirt than usual will be trapped in the filter and pressure may increase dramatically.
- The ingredients of this block are water-soluable and will dissolve within 15-21 days. Replenish with a new block thereafter to maintain your pool in a sparkling condition.
