For spa, hot tub, or heated pool owners, this 1 kg container of Bestway slow-release bromine provides effective disinfection without the characteristic smell of chlorine. Its formula remains effective even at high pH levels and high temperatures, two conditions common in heated pools where standard chlorine quickly loses performance. The result is water treated thoroughly, from the floor to the walls, in an environment where you can relax without olfactory constraints. Discreet maintenance for fully enjoying every session.
