Chlorine is essential for keeping your water clean, but not all chlorine is the same. From tablets to granules, each chlorine type from ClearWater has its own strengths depending on how you use your pool or hot tub, how you're maintaining it, and how you are using it.
Clearwater Chlorine Granules
What chlorine granules do:
These fast-dissolving granules are ideal for quick, effective disinfection. They kill bacteria, control algae, and break down organic contaminants like sweat, sunscreen, and oils.
How they’re used:
Granules are added directly to the water—no need for a floating dispenser. Just dissolve in a jug or bucket of warm water and pour evenly around the pool or hot tub.
How much to use:
- Pools and hot tubs: 2g of granules in 1,000 litres of water will raise chlorine by approximately 1ppm.
Always check your chlorine levels with test strips and adjust as needed. Aim for:
- Pools: 1-3ppm
- Hot tubs: 3-5ppm
When to use:
Granules are great for daily or weekly maintenance or when chlorine levels drop unexpectedly, such as after heavy use, or if the water quality drops. They are also essential for using as a shock dose when needed.

Clearwater Multifunction Tablets
What multifunction tablets do:
These slow-release tablets are a simple, hands-free option for maintaining chlorine levels. Each tablet disinfects the water, helps prevent algae, and maintains water clarity with a built-in flocculant.
How they’re used:
Tablets should be placed in a floating chemical dispenser, never directly into the water as they will not dissolve properly.
How much to use:
- Use 1-2 tablets in smaller hot tubs and pools. Chlorine dispensers have an adjustable flow rate. You’ll need to experiment a little with this to see which works best for you.
- Replace the tablet once it's fully dissolved—usually every 3-5 days, depending on water temperature and usage.
When to use:
Tablets are ideal for routine, hands-off maintenance. They’re perfect when you're away, or just want a consistent chlorine level without daily dosing.

Clearwater Fast Action Tablets
What fast action tablets do:
These small, quick-release chlorine tablets are a simple, that give a quick chlorine boost if your levels have dropped. Each tablet will dissolve in around 30 minutes.
How they’re used:
Tablets should be added directly into the water, making sure the filter system is circulating the water.
How much to use:
Each Fast Action Tablet raises chlorine ppm levels as follows:
- 600 litres raises chlorine by 2ppm
- 800 litres raises chlorine by 1.5ppm
- 1000 litres raises chlorine by 1.2ppm
- 1200 litres raises chlorine by 1ppm
When to use:
The Fast Action tablets are great if you want to use your pool or hot tub that same day and it needs a little boost to get it back in range.

Which One’s Right for You?
In many cases, a combination of both works best. Use tablets for regular upkeep, and granules when you need to quickly adjust levels or shock the water.
- Choose granules if you prefer flexibility, want faster results, or need to give your water a boost.
- Choose tablets for steady, long-term maintenance with minimal effort.
