Multifunctional Chlorine Tablets 200g

Slow dissolving 200g stabilised chlorine tablets that combine sanitiser, clarifier and algae control in one tablet. Sat in a feeder or floating dispenser they release a steady stream of chlorine to keep pool and spa water clean, clear and protected between test days.

• Delivers three actions in one tablet: chlorine sanitiser, water clarifier and algae control.
• Dissolves slowly for a steady free chlorine feed rather than a spike after each dose.
• Helps hold clarity by binding fine particles so the filter can trap them.
• Discourages algae from taking hold across the swimming season.
• Carries stabiliser, so the chlorine lasts longer in sunlight on outdoor pools.

How to use

1. Test free chlorine, pH and total alkalinity, and confirm pH sits at 7.2 to 7.6 first.
2. Balance the water before you start, as tablets work best in balanced conditions.
3. Load the tablets into an inline feeder or a floating dispenser; never drop them onto the pool floor or liner.
4. Set the feeder or dispenser flow to hold free chlorine in your target band.
5. Run the circulation pump so tablets erode evenly and the feed spreads through the water.
6. Test a few times a week and adjust the feeder rate or tablet count to keep the band steady.

Frequently asked questions

What does multifunctional mean here?

Each 200g tablet combines three jobs: it sanitises with chlorine, clarifies the water, and helps control algae, so one tablet covers all three.

Is this chlorine or bromine?

It is a stabilised chlorine tablet. Some early labels carried a bromine strapline in error; the product is chlorine based.

How do I dose these tablets?

Load them into an inline feeder or a floating dispenser and set the flow to hold your free chlorine band. Never place them straight on the pool floor.

How often should I test?

Test free chlorine, pH and alkalinity a few times a week and adjust the feeder rate or tablet count to keep levels steady.

Which size should I choose?

5kg suits smaller domestic pools, 10kg and 20kg suit larger or busier pools, and the 25kg tub is a bulk buy for commercial sites.

Is the 25kg a pallet item?

Yes. The 25kg tub ships on a pallet with a 6-tub minimum order, so it is set up for bulk and trade buyers.

Can I subscribe for repeat delivery?

Yes, subscription is available on the everyday sizes so tablets arrive on a regular schedule without reordering each time.

Are the tablets stabilised?

Yes. They carry cyanuric acid stabiliser, which protects the chlorine from sunlight and suits outdoor pools.

Do they affect pH?

Stabilised chlorine tablets are mildly acidic, so keep an eye on pH and rebalance to 7.2 to 7.6 as needed.

Can I use them in a spa or hot tub?

Yes, in a suitable dispenser and at a lower tablet count, though many spa owners prefer a smaller tablet for the volume.

Why is my chlorine low with tablets in the feeder?

The feed rate is probably too low or demand is high. Open the feeder or add a tablet, then retest after circulating.

Why is my stabiliser reading rising?

Stabilised tablets add cyanuric acid slowly as they dissolve. Part-refresh the water if it climbs out of range.

Multifunctional tablets or plain chlorine tablets?

Plain tablets only sanitise. These add clarifier and algae control in the same tablet, which cuts down on separate dosing steps.

Tablets or chlorine granules?

Granules give a fast lift but need dosing by hand each time. Tablets feed slowly through a device for a steadier, lower-effort routine.
