Essential Pool Chemicals Every Owner Should Keep on Hand
Introduction
The proper maintenance of a pool depends on fundamental chemicals rather than a large collection of advanced items. These essential chemicals in your toolkit will enable you to maintain safe water conditions and clarity and comfort throughout the entire season.
The essential pool chemicals that all pool owners need are explained in this expert guide which can be obtained from Deep Blue in different packaging options.
1. Chlorine (or Bromine)
Purpose: Kills bacteria, sanitises water, prevents algae.
Chlorine Tablets: Long-lasting, slow-release sanitiser
Granules: Fast-acting and adjustable dosing
Bromine Tablets: Ideal for spas and warmer water
2. pH Adjusters
pH+: The product elevates pH levels when the water becomes acidic (below 7.2)
pH–: The product lowers pH levels when water becomes too alkaline (above 7.6)
Maintaining a proper pH balance protects your equipment while providing better comfort for swimmers.
3. Alkalinity Increaser
Alkalinity stabilises pH. You should use Deep Blue’s Alkalinity Increaser to raise levels that fall below 80 ppm.
4. Calcium Hardness Increaser
Concrete and plaster pools require this chemical for maintenance. The substance prevents corrosion together with etching by maintaining calcium levels between 200–400 ppm.
5. Shock Treatment
The treatment functions to oxidize contaminants while refreshing the water and eliminating chloramines.
Chlorine Shock: Powerful and fast-acting
Non-Chlorine Shock: Gentle, chlorine-free option
6. Algaecide
The product stops and controls algae from growing. Our chemical solutions do not contain copper or produce foam thus being suitable for every pool surface type.
7. Clarifier
The product works to make cloudy water clear by binding tiny elements which can then be filtered out.
8. Metal Sequestrant
When your water contains iron or copper you need to apply Metal Control for preventing stains and colour changes.
9. Test Strips or Kits
Testing is essential. Deep Blue Test Strips should be used for testing essential levels 2–3 times weekly.
10. Filter Cleaner
Deep Blue Filter Cleaner serves to preserve filter efficiency while protecting against clogs during monthly cleaning operations.
