Pool Chemicals

Sigma Chemicals is your one stop shop for all of your home pool and spa chemicals.


Whether your pool is running a chlorine, salt, UV or mineral sanitization system, Sigma can recommend the best pool chemicals for you.  Our store keep a variety of chlorines (including our own high quality Sigma Liquid Chlorine), acids (including the popular Sigma No Fume), salts, and magnesium minerals.

Specialty Chemicals

On top of the sanitization chemicals, Sigma is the exclusive Western Australian distributor for the Pool Magic range of chemicals for balancing and stabilizing, algaecides, purifying, flocculants and shock treatments.  We even stock bug and duck deterrents!

Avoid lifting the cover to a green pool at the start of summer with a Winteriser to maintain your pool and prevent algae growth.  No need to start your pool chemicals from scratch at the start of the season.

Water Cleansing

New to Sigma, is the exciting Water Cleanser that will look after the health of your pool or water feature.  Classified by the APVMA as a ‘non-chemical’, this natural cleanser is safe to use in swimming pools, aquaculture and fish ponds to maintain the health of Bacillus (natural probiotic bacteria).  Bacillus produce enzymes that convert phosphates to polyphosphates which breakdown large waste particles creating a more functional filtration system, requiring less maintenance.  For further information on the Water Cleanser, check out the page here.


Although Sigma provide a FREE pool and spa water testing service, we also sell home test kits, along with all the reagents and refills, for when you just cant make it into the store.
