Diatomix Garden Pond – Natural Algae & Water Quality Treatment for Small & Ornamental Ponds

Diatomix Garden Pond is specially formulated for backyard and ornamental ponds up to ~10 m². It’s a safe, nutrient-based solution that helps beneficial diatoms outcompete nuisance algae, reduce excess nitrogen & phosphorus, improve water clarity and enhance overall pond health — without harsh chemicals or risk to fish, pets and wildlife.

Key Benefits:
  • Improves water clarity and reduces slimy algae
  • Enhances dissolved oxygen and supports aquatic life
  • Safe for fish, pets, birds and plants
  • Easy to apply — perfect for home ponds and water features
Why Garden Ponds Get Algae Problems

Many backyard ponds struggle with:

  • Uneven nutrient loads from fertiliser run-off or leaves
  • Stagnant water which fuels algae growth
  • Poor natural nutrient cycling
  • Low populations of beneficial microorganisms

When these conditions persist, algae and slimy growth appear — marring appearance and stressing pond life.  Diatomix Garden Pond helps restore ecological balance by accelerating the growth of beneficial diatoms that naturally absorb the nutrients that fuel nuisance algae.

How It Works

Diatomix Garden Pond contains bioavailable silica and essential micronutrients that stimulate diatom growth — microscopic algae that are beneficial to pond ecosystems.

These diatoms:

  • Absorb nitrogen and phosphorus (nutrient “fuel”)
  • Improve water clarity
  • Support oxygen production
  • Become natural food for zooplankton and small aquatic life

Unlike algaecides that kill algae, Diatomix helps nature keep undesirable algae and waterweeds from dominating in the first place.

How to Use

We would advise you to dose your pond starting with approx. 20 mL per week and reduce this amount to 10 – 15 mL as results begin to show, you should find the suitable maintenance dose which may vary from time to time depending on weather conditions and the amount of nutrients (leaves, weeds, fertilizer run off or fish food) entering your pond.

Apply three times per week until improvements are seen.  This does mean your doses are quite small.  7 mL three times per week = 21 mL.

Stir or shake bottle before use.

When You’ll See Results

Results can vary with conditions, but common outcomes include:

  • Noticeable reduction in green water within days
  • Clearer water over 1–3 weeks
  • Less green slimy algae and surface scum
  • Fish appear more vibrant and active
Available in 1 Litre bottle and is ideal for small garden ponds where it should last for approximately 1 year as only small amounts are needed each time.
