The next development of Jolly Gel Pool Flocculent by Mineral Supplies International (MSI) introduces a flat pack version of the product. The new flat pack means it will be cheaper to post individual packs to customers. The attractive dark blue flat pack also has great shelf appeal for walk-in customers to pool retail shops. Jolly Gel is renowned for quickly restoring pool water back to sparkling clear condition. This popular flocculent eliminates phosphates and removes even the finest microscopic particles of debris from pools.
