When used in swimming pools with a counter-current or massage system, the absolutely foam-free Algicid should be used. In fact, the problem occurs when third-party products are used - for cleaning, for example. Household and universal cleaners in particular contain foaming substances that enter the pool water quite automatically.
In the pH range from 7.0 to 7.4, the BENAMIN Ultra Clear unfolds the greatest effect, especially in the area of flocculation and algicide.
The filter pump should be able to circulate the entire pool contents twice a day. Our pool experts will be happy to help you here with expert advice.
To dose water care products correctly, it is important to know the exact amount of water (m³) in the pool. This can be calculated as follows:
  • Rectangular pool: length (m) x width (m) x average water depth (m) = pool capacity (m³)
  • Round pool: Diameter (m) x diameter (m) x average water depth (m) x 0.78 = pool capacity (m³)
  • Oval pool: Max. Length (m) x Width (m) x Average water depth (m) x 0.89 = Pool capacity (m³)
  • Octagonal or freeform pools: Max. Length (m) x max. width (m) x average water depth (m) x 0.85 = pool capacity (m³)
Generally speaking, no, the BENAMIN Ultra Clear contains all the components of required pool chemicals and doses them independently for optimal BWT pool water.
The flocculant was added too quickly or the reaction time (switch off the filter system for approx. 15 minutes) was not observed. Therefore, the flocculation only took place in the swimming pool. Remedy: Switch off the filter system, allow the flocs to settle and vacuum carefully.
Milky-cloudy water indicates lime precipitation due to a pH value that is too high (even if only once). Coloured turbidity is caused by organic impurities. A shock disinfection with chlorine or active oxygen after pH correction followed by flocculation makes the water clear again. For prevention, we recommend flocculation cartridges.
This is algae growth in an advanced stage. First, the parts of the pond with less flow (corners) are attacked. The colouring corresponds to the respective type of algae (e.g. green algae). The only thing that helps here is a shock disinfection with chlorine or active oxygen after the pH value has been adjusted.
Bad chlorine odours usually occur when there is too little free chlorine (less than 0.3 mg/l) in the water. This can be remedied by replenishing the fresh water and adding virtually soluble chlorine to a free chlorine level of 0.5mg/l.
With green water, always carry out shock chlorination. BWT AQA marin Algicid is a preventive product.
The proportion of flocculation in the Ultra Clear binds the smallest dirt particles (sand, dust, sweat, etc.) in your pool into larger particles. These can be better caught by your sand filter, making your pool water clearer, more hygienic and cleaner. The flocculant requires a pH range of 7.0 to 7.4 in order to develop its effect optimally.
Yes, you should also check your pool water at regular intervals (at least 1x per week) when using a multifunctional product such as the BENAMIN Ultra Clear. Our digital pool tester 5 in 1 or the BWT ICO Station as a smart pool tester can support you in this.

The skimmer here is the most central and best place to position the Ultra Clear, either with the lid open or with the lid drilled several times to get even water circulation.

If you don't have a skimmer, there is still the option of placing the Ultra Clear in our AQA marin dosing float and adding it directly to the pool or, in the case of pools with circulation channels, to the equalisation tank.

The algicide content in the BENAMIN Ultra Clear preventively prevents algae growth in your pool. This prevents unsightly green deposits in the form of green algae in your pool and pool water. All BWT Algicides are foam-free and therefore also suitable for counter-current systems. In case of very strong algae infestation of the pool with greenish water and deposits, a shock chlorination should be carried out (with ongoing circulation) and then preventively use e.g. AQA marin Algicid.
