Can I use Mineral Swim Dead Sea minerals in my spa?

The heat in spas has no bearing on the Mineral Swim system and that the water clarity and health benefits are the same. We’re currently testing Mineral Swim for use in spas with cartridge filters (normal high-flow filters commonly used with spas). This R&D is focusing on the effect of flocculants as they do their job and accumulate with other 'contaminants' (ie sand, dirt and hair). We have not uncovered any issues and testing continues.
