  • First perform a backwash.
  • Before adding, check the pH-value with BAYROL test strips and, if necessary, adjust it to the ideal range of 7.0 to 7.4. The optimum chlorine level is between 0.5 and 1 mg/L.
  • Dose the Chlorilong® ULTIMATE7 through the skimmer only while the circulation pump is running.
  • The blue part of the tablet quickly disintegrates and "burns" the dirt remaining in the filter despite backwashing.
  • The white part of the tablet maintains 30 m³ of water evenly over about 7 to 10 days.

Tip: As protection against algae growth, we recommend to add Desalgine® Jet regularly to add. 

Important Notes: Never throw Chlorilong® ULTIMATE7 tablets directly into the pool due to risk of bleach stains. Be sure to avoid direct contact with non-chlorine resistant materials.

Chlorilong® ULTIMATE7 is a two-phase chlorine tablet à 300 g with 7 functions for an optimal and permanent disinfection of pool water and filter. Fast dissolving blue layer: shock action on pool and filter. Slow and regular dissolving white layer: permanent disinfection, anti-algae, clarifying, anti-scaling and chlorine stabilizer.

Chlorilong® ULTIMATE7 (formerly Varitab®) consists of two phases with 7 functions: disinfection, algae prevention, turbidity removal, scale prevention, chlorine stabilization, shock treatment and filter shock treatment.

The two phases of Chlorilong® ULTIMATE7 have different functions :

The blue part decomposes in about 10 minutes and deposits on the filter bed of the sand filter. This causes an intensive disinfection of the filter material. Dirt and bacteria are thus safely removed.

The white part of the tablet is slowly soluble and provides a permanent disinfection.

The included Silk effect formula enhances the antiscale effect and ensures silky-smooth pool water. Without copper sulfate: prevents damage to the pool surface.

Frequently asked questions (FAQ)

  • You can bathe again a few hours after adding the tablets. Preferably dose the tablets in the evening after bathing.

  • High water temperatures, intensive bathing or even thunderstorms can cause faster degradation and therefore higher consumption of disinfectants. This can lead to the formation of algae, cloudy water and even slimy deposits. If these symptoms are already recognisable, shock chlorination with Chloryte®, Chlorifix® or Chloriklar® can help.

  • The dissolution speed depends on the water flow in the skimmer, the daily filter runtime and the water temperature. The higher the flow rate and/or the longer the pump runs and the higher the temperature, the faster the chlorine tablet is consumed. Conversely, the lower the flow rate and the shorter the pump runs, the slower the tablet will dissolve. Adjust the dosage according to the measured chlorine content.
