PTP-ProTectPlanet
PTP-ProTectPlanet is a natural bio-enzymatic blend of bacterial spores, enzymes and nutrients. After application, it starts the biological breakdown of organic deposits on the bottom and in the water column. The work is done by naturally occurring, non-GMO aerobic and facultative anaerobic bacteria.
The bacteria consume phosphates, nitrites and nitrates, which would otherwise feed algae and cyanobacteria. The water gradually clears and its dissolved oxygen content increases. The result is a clean, healthy and balanced aquatic ecosystem. We select the specific product, dose and method based on your water conditions.
Year-round care
Year-round product
A product in water-soluble packets that are placed in the water unopened. It is effective from 4 °C, so it can also be used in spring and autumn.
Request a care proposalWe do not apply the products during frost. We choose the right product and timing based on water temperature and site conditions.
What happens after application
- Within a few weeks, the water regains its biological balance.
- Levels of phosphates, nitrites and nitrates, the nutrients that feed algae and cyanobacteria, decrease.
- Chlorophyll a, a measure of algae concentration, decreases and the water stops turning green.
- Organic sludge decreases, with an expected reduction of 20 to 30 cm per year, and the whole water column becomes clearer.
- Dissolved oxygen rises to 5 to 12 mg/l, a level that is essential for fish and plants.
When changes become visible
This is a safe biological process and it needs time. The first results usually become visible after a few weeks. The pace of change depends on water temperature, the amount of sludge and nutrient inputs from the surroundings.
What does the CASSCO manufacturer documentation state?
Composition. CASSCO Pond Bacteria 5X concentrate contains seven strains of Bacillus bacteria (B. subtilis, B. megaterium, B. licheniformis, B. amyloliquefaciens and B. pumilus). They produce enzymes that break down proteins, starches, fats, cellulose and lignin, the main components of organic sludge. The blend also contains pulverised barley straw, which helps maintain water clarity.
Effect. According to the label, the product eliminates murky water, bottom sludge and odours and reduces excess phosphate and nitrate from natural sources or fertiliser run-off.
Conditions. The blend is effective at pH 4 to 10. The manufacturer states effectiveness at water temperatures of approximately 2 to 38 °C. To allow a margin, we apply the year-round product from 4 °C. According to the manufacturer, all ingredients are biodegradable.
Safety. In a letter dated 4 May 2021, the manufacturer confirms that all strains are naturally occurring, non-pathogenic and non-GMO and represent no pathogenic hazard to plants, animals or humans. The independent laboratory Microcheck (ISO 17025 compliant) classified each strain at the lowest biosafety level, BSL 1.

03 / How it works
A natural process in three steps.
Targeted application by boat
We usually apply the product from a boat at predetermined locations. Organic sediment is not evenly distributed, so we assess the site before allocating the dose. Deeper and central areas are considered as well. Application from the shore is also possible where access and conditions allow.
Positive chemotaxis
Supplier’s descriptionThis is the ability of cells or organisms, including bacteria, to move towards a chemical stimulus. The supplier describes bacteria moving towards higher concentrations of nutrients and organic waste, using receptors to locate the target and move towards it immediately.
Biological activity
Supplier’s descriptionThe supplier describes bacteria immediately starting to break down organic waste in the water column and on the bottom, while reproducing under optimal conditions. The process then needs time.
The pace of biological activity depends on temperature and conditions in the lake. The summer product is sprinkled directly onto the surface. The year-round product CASSCO 5X is applied in sealed water-soluble packets that are not opened.
04 / Climate · A subject that deserves attention
The issue goes below the surface.
Earth is our only home.
Organic sediment is about more than a lake’s appearance. Where there is no oxygen on the bottom, its decomposition produces methane. That is why we also care about what happens below the surface.
Less sludge, less room for methane.
Methane forms where organic matter decomposes without oxygen. In a lake, this happens mainly in thick layers of sludge on the bottom. Biological care gradually breaks these deposits down. As the sludge decreases, so does the environment in which methane forms. A clean bottom benefits both a healthy lake and its surroundings.
Methane · CH₄
Methane forms during microbial decomposition of organic matter without oxygen. Per unit mass, its global warming potential is about 80 times that of CO₂ over 20 years. It remains in the atmosphere for roughly a decade.
Carbon dioxide · CO₂
In a lake, carbon accumulates mainly in the organic sludge on the bottom. Where sludge decomposes without oxygen, it produces methane instead of CO₂, and methane has a much stronger warming effect. The less sludge remains on the bottom, the less material can turn into methane.
Hydrogen sulfide · H₂S
Sulfate-reducing bacteria produce it in oxygen-depleted sediments. It causes a rotten-egg smell and can be toxic to aquatic organisms.
Nitrogen compounds
For water quality we monitor nitrite (NO₂⁻) and nitrate (NO₃⁻), which feed algae and cyanobacteria. Nitrous oxide (N₂O) is a greenhouse gas.
Sources on gas properties: UNEP – methane, EPA – atmospheric lifetime, USGS – methane production in lake sediments.
05 / Dosage
The right dose for your water.
Each body of water needs its own plan. We determine quantities and application locations individually, considering surface area, depth, organic sediment thickness and distribution, pollution, pH and water temperature. Manufacturer recommendations are a starting point, not a universal dose for every lake.
- The type and location of your water body or tank.
- Approximate area and depth, or volume.
- Your concerns: cloudy water, odour or organic deposits.
- Recent photographs and water temperature, if known.
- If you already have a product, a photograph of its name and label.
- Sediment thickness and distribution, pH and available measurements, if known.
Don't have exact figures? An estimate is enough to get started.
Individual planning respects the conditions of use and safety restrictions of the exact product. If a different approach is needed, it is assessed with the manufacturer first; this is not a licence to disregard instructions.
06 / Safety
The right product and correct use.
The safety of water and the life within it matters to us. Every application is planned individually, considering the specific product, location and water use.
Fish and aquatic plants
PTP products and CASSCO Pond Bacteria 5X are designed for aquatic environments. The manufacturer labels them as safe for fish and plants. The bacteria used are naturally occurring and non-pathogenic.
Bathing sites during the season
We agree the timing and method of application with the operator so that the bathing site can keep operating. The manufacturer confirms that the bacteria used represent no pathogenic hazard to people or animals. We apply the product according to its instructions.
Protected sites
The product is of natural origin, so it can also be used in protected areas. Where a site is subject to a higher level of protection, we obtain consent from the competent nature conservation authority in advance.
Handling and storage
We follow the label and safety instructions. Store the products in a cool, dry place out of reach of children. Protect them from frost and from temperatures above 40 °C.
According to its label, CASSCO Pond Bacteria 5X is not intended for water for human consumption.
What do the bacterial culture assessments say?
Seven Microcheck assessments from 2012 to 2013 classify the cultures examined at the lowest biosafety level, BSL 1. Such microorganisms do not normally cause disease in healthy people.
The assessments also advise caution for people with weakened immune systems. That is why we always plan applications at bathing sites together with the operator.

FAQ
Questions we hear most often.
Can a lake or pond be desludged without dredging?
Yes. In biological desludging, bacteria gradually break down organic sludge directly on the bottom. There is no need to drain the water or bring in heavy machinery, and fish stay in the water. Where there is a large amount of sludge, application may be needed for several consecutive years. Bacteria do not break down inorganic deposits such as sand or clay.
How long before I see results?
A natural process has its own pace. You will see the first changes within weeks and the full effect over the season. Where there is a large amount of organic sludge, application may be needed for several consecutive years. The result is worth it.
How is the product used?
The summer product is sprinkled directly onto the water surface at pre-selected spots at water temperatures of 10 to 40 °C. The year-round product comes in water-soluble packets that are not opened. They are placed directly into the water at several locations, dissolve within minutes and are effective from 4 °C. Send us the surface area, depth and a description of the problem and we will propose the dosage free of charge.
Can it be overdosed?
We base the dose on surface area, depth and level of pollution and on the manufacturer’s recommendation. The product contains only naturally occurring, non-pathogenic bacteria that the manufacturer labels as safe for fish and plants. There is therefore no need to worry about overdosing.
Is the product safe?
The manufacturer confirms that all bacteria used are naturally occurring, non-pathogenic and non-GMO and represent no pathogenic hazard to plants, animals or humans. An independent laboratory classified them at the lowest biosafety level, BSL 1. The product is safe for fish and aquatic plants. At bathing sites, we agree the timing with the operator.
How should the product be stored?
In a cool, dry place out of reach of children and away from food. Protect it from frost and from temperatures above 40 °C.
