Bromine or Chlorine Advice

The 2 most common sanitisers are chlorine and bromine, each has their own advantages & disadvantages which we have listed below.

Bromine

Bromine comes in a tablet & granule form these are used with a floating dispenser which floats on the surface of the hot tub water & slowly disperses bromine into the hot tub.

This enables the status of the bromine in the hot tub to be easily maintained by keeping the tablets topped up in the dispenser at all times.

Bromine is a softer option than chlorine and would be recommended if you or a family member/friend have sensitive skin as chlorine can be harsher on the skin and eyes.

Bromine tablets also have less of an odour than chlorine, although chlorine scents only become strong when water becomes dirty.

The main disadvantages of bromine is that is very slow to dissolve in comparison to chlorine and especially in hard water areas.

Chlorine :

Chlorine is very easy and fast to dissolve so works quicker than bromine in all water types.

Chlorine is also cheaper to buy and gives the water a clearer and crisper look, water with bromine can look a little dull by a comparison.

The downside of chlorine is the strong scent it gives but this is usually as the water is not clean (e.g public swimming pools) and it is harsh on sensitive skin types.

Unlike the dispenser which lets you monitor how much bromine is required, chlorine needs the use of testing strips and is more chemical based analysts to test the levels to know if more granules need to be applied.

.......and what about Chlorine Tablets?

We do not recommend chlorine tablets for a spa or hot tub, this is because chlorine tablets are a trichlor product.

TriChlor tablets dissolve very fast in comparison to Bromine tablets & decrease the ph.

Hot tub water that is low in pH can be corrosive to pumps, jets, heaters & damage the hot tub shell both above & below the surface.

Please note: Use of TriChlor in spas/hot tubs is not recommended by many in the industry.

At Hot Tub Suppliers the use of TriChlor by customers will void the warranty.
