How long does one tablet last?

5-7 days under normal skimmer flow.

Where do I put the tablet?

Skimmer basket or pump strainer; never broadcast loose into the pool.

How many for my pool?

1 tablet per 30-40 m³ per week. Larger pools dose 2-3 tablets weekly.

Single 36-tablet tub, enough for roughly a full UK swim season at 1 tablet per skimmer per week.

Liquid for haze recovery; tablets for routine prevention. Use both as the season demands.

Will it work with my sand filter?

Yes. Particularly useful on sand filters because their 20-micron cut-off lets fines through.

What is the active ingredient?

Aluminium sulphate coagulant in 50 g slow-release tablets.

Does it consume chlorine?

No. Aluminium sulphate is a coagulant; chlorine bank is unaffected.

How much aluminium sulphate per tablet?

Roughly 40 g of aluminium sulphate per 50 g tablet, balance is binder and slow-release matrix.

Tablet not dissolving?

Check skimmer flow and pump runtime; cold water also slows release.

Add a one-shot liquid dose; tablets prevent rather than cure heavy haze.

Tablets vs liquid clarifier?

Tablets for set-and-forget weekly cover; liquid for emergency haze recovery. Different jobs.

Tablets vs flocculant?

Tablets keep particles in circulation for filter capture; flocculant drops them to the floor for vacuuming. Tablets are routine, floc is emergency.
