Targeted Clarity Through Filter-Assisted Flocculation
Lo-Chlor Sparkle Pill is a concentrated clarifier and flocculant tablet developed to clear cloudy pool water efficiently while supporting ongoing water clarity through normal filtration.
Formulated using aluminium sulphate, Sparkle Pill works by coagulating ultra-fine suspended particles into larger clusters that are more readily captured within the filter media, creating an additional filtration layer that enhances fine particle removal.
Designed for simple skimmer-box application, Sparkle Pill is particularly effective in pools using sand or glass filter media, providing a controlled, easy-to-use solution for restoring and maintaining clear, polished water.

Features & Benefits
- Clarifier and flocculant tablet – combines particle coagulation with enhanced filtration capture.
- Highly concentrated aluminium sulphate – delivers strong flocculating performance in tablet form.
- Works particularly well with sand and glass filters – supports improved fine particle capture.
- Fast dissolving – activates quickly during normal filtration.
- No sticky residue – dissolves cleanly without mess.
- Individually packaged in a cloth sock – controlled dosing and easy handling.
- Easy skimmer box application – no pre-mixing or measuring required.
How It Works
Cloudy pool water is often caused by microscopic particles that are too small to be removed efficiently by filtration alone.
Lo-Chlor Sparkle Pill releases aluminium sulphate into the water as it dissolves in the skimmer basket. This creates strong coagulating and flocculating action, binding fine particles together and forming an enhanced filtration layer within the filter media.
As water passes through the filter, these combined particles are captured more effectively, resulting in clearer water through continuous filtration rather than sediment drop-out.

How to Use
- Backwash the filter thoroughly before application.
- Test and adjust pool water so pH is between 7.2 and 7.6.
- Place the required number of Sparkle Pills (inside their cloth socks) directly into the skimmer basket.
- Run the filtration system continuously for 24 to 48 hours.
- Backwash the filter if required after treatment.
- Remove the empty cloth sock from the skimmer basket once the tablet has fully dissolved.
Dosage & Coverage
- 1 tablet: per 50,000 litres of pool water after every backwash.
- 2 tablets: for pools between 50,000 and 100,000 litres.
Important Usage & Compatibility Information
- Optimised for use with sand and glass filter media.
- Can also be used with cartridge filter systems.
- Must be applied via the skimmer basket while the pump is running.
- Ensure pH is within the recommended range before treatment for best results.
- Backwashing after treatment helps restore normal filtration performance.

Frequently Asked Questions
Is Sparkle Pill a clarifier or a flocculant?
Sparkle Pill combines clarifying and flocculating action. It coagulates fine particles and enhances filtration capture rather than causing debris to settle on the pool floor.
Does Sparkle Pill require vacuuming to waste?
No. Sparkle Pill is designed to work through the filtration system. Captured material is removed by normal filtration and backwashing.
Which filter types is Sparkle Pill best suited to?
It works particularly well with sand and glass filter media, and can also be used with cartridge filters.
Can Sparkle Pill be used for ongoing clarity maintenance?
Yes. When used after backwashing, Sparkle Pill can help maintain water clarity as part of regular pool care.
Can I swim after adding a Sparkle Pill?
Sparkle Pill is applied via the skimmer basket and works through the filtration system rather than directly in the pool water. Swimming can generally resume once the tablet has dissolved, the filtration system is running normally, and water balance is within recommended ranges. As with any pool treatment, routine water testing is recommended before swimming.
Do I need to backwash after using Sparkle Pill?
Yes. Sparkle Pill enhances filtration capture, so backwashing after treatment helps remove collected material from the filter and restore normal filtration performance. Backwash timing will depend on pool conditions and filter pressure.
