While Bromine remains difficult to acquire, you may use Bromine Super Tabs in place of the mini Bromine Tabs. This option is great for pools, swim spas, and hot tubs over 2000L of water.
One Bromine Super Tab does the work of 4-5 mini Bromine Tabs and the supply will last you much longer.
Oxygen is a powerful oxidizer. Once it is administered, wait 1 hour before swimming. A great treatment after a long day of swimming!
Swim Spa Oxygen $98
