Biofoam for garden pond

⚙️ HOW BIOMOLYTAN WORKS
1️⃣ Biological filtration

Biomolytan provides a large surface area for the growth of nitrifying bacteria, which convert:

Ammonia (NH₃) → Nitrites (NO₂⁻) → Nitrogen (NO₃⁻)

This process reduces the toxic load in the water and supports the health of fish and plants.

2️⃣ Mechanical filtration

The coarser biomolytan captures larger impurities such as plant debris, algae and fish excrement.

It can be rinsed and reused during regular maintenance.

3️⃣ Ecosystem stabilization

The porous structure allows the formation of a biofilm, which improves the biochemical balance of the water.

Supports a healthy microbial environment, which reduces algae growth and sludge formation.

🏠 BIOMOLYTAN CLAIMS
💧 Water

Biomolytan is suitable for most garden ponds:

Temperature: 4–35 °C

pH: 6.5–8.5

GH/KH: medium to hard water

⚙️ Environment

Place it in chamber filters, pressure filters or separately in filter containers.

It can also be used as an insert in garden waterfalls or skimmers.

🧹 Maintenance

Rinse in pond water or slightly in warm water 1× every 2–4 weeks to remove sludge and maintain beneficial microflora.

Do not use chemicals because they kill nitrifying bacteria.

🧠 CHARACTERISTICS

Passive material - does not consume anything on its own and does not produce toxins

Non-aggressive - does not harm fish or plants

Works only in conjunction with biological life that attaches to it

🧱 TYPES OF BIOMOLYTAN
1️⃣ Coarse molytan

Large pores, captures larger impurities

Used as the first mechanical filtration

2️⃣ Medium molytan

Combination of mechanical and biological filtration

Suitable for most garden ponds

3️⃣ Fine molytan

Small pores, ideal for the growth of nitrifying bacteria

Used in the upper part of the filter or as a bio insert

4️⃣ Combined with bio-chambers

Molytan can be part of multi-stage filters, where the coarse one captures sludge and the fine one supports bacteria

🩺 IMPACT ON HEALTH POND
POSITIVE

✔️ stabilizes water quality
✔️ reduces ammonia and nitrite levels
✔️ supports fish and plant health
✔️ prevents algae and sludge formation
✔️ extends the life of mechanical filters

NEGATIVE / COMMON PROBLEMS

❌ clogged foam can reduce filtration efficiency
❌ beneficial bacteria die when cleaned in water with chlorine or chemicals
❌ unsuitable material can release dust or chemical residues

⚖️ ADVANTAGES AND DISADVANTAGES
👍 ADVANTAGES

✅ highly efficient biological filter
✅ supports a healthy microbial environment
✅ easy maintenance - rinse and reuse
✅ compatible with various types of garden ponds
✅ water and frost resistant

👎 DISADVANTAGES

❌ requires the presence of nitrifying bacteria - does not filter chemically on its own
❌ clogged foam can cause flow slowdown
❌ with improper maintenance efficiency may decrease

🛒 HOW TO CHOOSE THE RIGHT ONE

Pore size – coarse for mechanics, fine for biofiltration

Filter type – pressure, chamber, separate – depending on the location in the pond

Quantity – depending on the volume of water and the number of fish

Material quality – without chemical additives, stable and non-toxic

Maintenance – simple, rinse once every 2–4 weeks

📌 Tip: the combination of coarse and fine biofoam is ideal for larger garden ponds where you want to optimize mechanical and biological filtration at the same time.

🧭 PRACTICAL TIPS

When using it for the first time, it is advisable to rinse the biofoam with pond water to remove dust.

Do not use chemicals or chlorinated water when cleaning.

In combination with biofilters and pressure filters, it can significantly reduce algae formation.

Regularly check that the filter elements do not become clogged with sludge, which reduces efficiency.

📌 SUMMARY

Biomolytan is a versatile and effective material for biological filtration of a garden pond.

Supports the growth of beneficial bacteria and stabilizes water quality

Filters mechanically and biologically

Easy to maintain, frost and water resistant

Choosing the right type and maintenance are key for maximum effect
