4. Microorganisms Against Pond Algae – BioTeich Aktiv is the Natural Solution for Clear Water
Almost every pond owner dreams of an idyllic, clear water paradise in their garden. However, in many cases, this dream is disrupted by murky water and algae. The constant worry about water quality and the effort involved in using algae killers, UVC lamps, and other aids – which ultimately disappoint in the long run – can leave many pond enthusiasts feeling frustrated. In this case, there is a natural and sustainable solution: Specialized microorganisms against pond algae! These tiny, invisible helpers break down excess nutrients before algae can spread. The result: a balanced, healthy pond ecosystem and crystal-clear water. In the fourth part of our guide series, you’ll find all the important information, solutions, and tips.

🌱💧 FAQ: Microorganisms against algae in the pond
Welcome to the expert area on natural microbiology and BioTeich Aktiv. Here you will learn how microorganisms build up the biological balance in the pond and permanently suppress algae in a natural way.
Why are microorganisms against algae in the pond so important?
Every pond contains algal spores. Whether they develop into visible algae depends on three factors:
- ⚠️ Excess nutrients (nitrate, phosphate, etc.)
- 💧 Oxygen deficiency
- 🥝 Non-activated microbiology
If the beneficial microorganisms are missing, nutrient breakdown does not occur – and algae gain the upper hand. That is why an intact microbial system is the most natural weapon against algae in the pond.
Why do I need to use microorganisms at all?
Your pond is a body of water created by human hands. To prevent the pond water from seeping away, ponds are sealed with pond liner, rubber, GRP or concrete – your pond is therefore a closed system with no connection to a stream, lake or river. This means that these various natural microorganisms cannot settle in your pond on their own.
If you have already:
- ✅ determined the best water source for filling the pond,
- ✅ corrected non-optimal water values and
- ✅ maximized the performance of your pump and filter system,
... then you can now start building the self-regulating microbiology in your pond. This creates a perfect system against algae in the pond that helps in the long term and sustainably.
💡With BioTeich Aktiv you can restore the biological balance of your pond in a purely biological way. All you need to do is dissolve the natural microorganism mixture in a bucket of pond water once a month and distribute it evenly over the pond surface or add it directly to the filter.
✅ Effective protection: Natural microorganisms against algae in the pond reliably combat any green turbidity
✅ Easy to use: One monthly application during the pond season is sufficient
✅ Environmentally friendly: Bacteria against algae reliably protect the biological balance – completely without chemicals!
✅ Long-term effect: The microorganisms against algae in the pond promote a stable and healthy ecosystem.
How do the microorganisms in BioTeich Aktiv work?
BioTeich Aktiv contains a highly effective mixture of effective microorganisms that perform three tasks:
- ♻️ Breakdown of organic pollutants
- 🔄 Removal of nutrients before algae can use them
- ⚖️ Activation of the nitrogen cycle: Ammonium ➔ Nitrite ➔ Nitrate ➔ gaseous nitrogen (escapes)
The result: A healthy, clear pond without an algae plague – completely without chemicals!
How do I use BioTeich Aktiv correctly?
- 🧹 Dissolve 2g per 1,000 liters of pond water in a bucket of pond water once a month
- 🌊 Distribute evenly over the water surface or add directly to the filter
- ⏰ For new installations, after filter cleaning or heavy algae infestation: 2 applications at 15-day intervals
🚀 Natural algae stop couldn’t be easier!
What are common causes of algae growth?
- 🐟 Too many fish
- 🍼 Overfeeding
- ⛈️ Fertilizer and rainwater inputs
- 🍃 Decomposed plant residues, autumn leaves
- 🤺 Sludge layers on the pond floor
🔗 Tip: Use the BioTeich Sludge Removal Set to specifically prevent the formation of nutrient-rich deposits.
Which types of microorganisms work against algae?
BioTeich Aktiv contains several groups of microbes, including:
- 💧 Denitrifying bacteria: convert nitrate into nitrogen gas
- 🥝 Special microorganisms: are nutrient competitors of algae with 200 times faster reproduction
- 🌞 Photosynthetic bacteria: use sunlight for water purification
- 💉 Nitrifying bacteria: convert ammonium ➔ nitrite ➔ nitrate
Why is a UV-C lamp problematic for your natural pond?
💡 A UV-C lamp emits ultraviolet light in the C range. This prevents the cell division of microorganisms – this affects not only harmful but also beneficial bacteria. The consequences:
- ❌ All microorganisms are killed – including those important for natural water purification
- ❌ New nutrients are created when suspended algae die, which can promote filamentous algae
- ❌ The biological balance is permanently disrupted
📉 Although UV-C lamps achieve visible clarity in the short term, they damage the entire ecosystem of your pond in the long term. When algae die, nutrients such as phosphate are released, which additionally promote the growth of other types of algae (e.g. filamentous algae). At the same time, the UV light also destroys beneficial clear-water bacteria in the pond – a vicious cycle begins.
🌱 Our recommendation: Do without UV-C technology and rely on biological regeneration with BioTeich Aktiv and the high-performance filter material BioTeich MAXIMUM. The natural microorganisms break down nutrients, activate the nitrogen cycle and maintain a stable balance – completely without side effects.
When is double use of BioTeich Aktiv particularly useful?
- ❄️ After the winter break (from 10 °C water temperature)
- 🌟 When setting up a new pond or at the start of the season
- 🚿 After cleaning the filter
- 🔌 After a power outage of more than 2 hours
- 🐟 After using fish medication
- 🤺 In the case of increased algae growth
- ⚠️ After a partial water change of more than 40%
