## Description

FS Biological activator Product Septic tank treatment Bacteria and enzymes Removes odors Improves filtration Reduces emptying Cleans downpipes Eliminates nuisances (FS1, 450, gram)

## Features

- Natural, biological enzymatic product Helps break down solid organic waste into liquids Prevents odours Reduces sludge in the pit Improves filtration of liquids into the ground Reduces the number of pit emptying/cleanings.
- Neusol FS is a biological mixture with enzymes and micronutrients with more than 1000 million microorganisms per gram Specific enzymes (lipase, protease, cellulase among others) break down oils, fats, starch, proteins, cellulose... Clogs, obstructions and odors are avoided
- Maintenance, Modern lifestyle habits (processed food, cleaning and personal hygiene products, etc.) contain elements that hinder the correct functioning of septic tanks / cesspools and that is why they need to incorporate products that counteract the harmful aspects. The regular application of Neusol FS allows the tank to work in the best possible way: liquefying and filtering without generating odors.
- Application: We recommend applying the product in the kitchen sink to keep the pipes free of oil and grease, avoiding the accumulation of food residues that cause blockages and bad odours. Mix the appropriate amount of Neusol FS with 2 litres of water, stir and empty. The best time to use it is at night when the sink will be without water for several hours.
- Neusol FS acts directly on the source that generates bad odors (prevents fermentation) it is a maintenance product Depending on the initial state of the pit, the results may take days or weeks to be observed.
- For very intense or punctual odours we recommend the application of Neusol W2, for immediate neutralisation of odours. It is a natural product based on natural and synthetic extracts that act directly on odours (not on the cause) neutralising them immediately.
- Dishwashers We can also use Neusol FS in the dishwasher to prevent odours and blockages. Apply 1/2 spoon mixed with 1/2 l of water once a month.
- Motorhome when you start a trip, put 1/2 spoon in the sewage and grey water tanks to prevent the formation of odors and facilitate the decomposition of solids.
