Full Description

Treats up to 50,000 Litres – One 1L bottle of HouseProud Pond Algae Clear treats up to 50,000 litres of pond water, making it one of the most cost-effective natural pond treatments available. Simply measure 20ml per 1,000 litres, mix with pond water in a bucket or watering can, and distribute evenly across the pond surface. Repeat weekly to maintain clearer, healthier water all year round.

Works all year round, Down to 4°C – Unlike many pond treatments that become ineffective in cooler months, HouseProud Pond Algae Clear uses a specially formulated living bacteria blend that remains active in water temperatures as low as 4°C. This means you can treat your pond through autumn and winter when sludge and organic waste build-up is at its worst, getting ahead of green water problems before spring arrives.

Natural Bacteria Formula - Our beneficial bacteria blend actively targets the root cause of green water by digesting organic sludge, dead plant matter, and the excess nutrients that feed algae growth. Rather than masking the problem with harsh copper-based chemicals, it works with your pond's ecosystem to naturally restore water clarity and reduce algae, blanket weed, and surface scum over time.

Fish, plant & wildlife safe – Formulated without harmful chemicals, HouseProud Pond Algae Clear is completely safe for use in ponds containing fish including koi and goldfish, aquatic plants, and visiting wildlife. It is suitable for use with or without a filter system, making it ideal for garden wildlife ponds, ornamental ponds, and koi ponds alike. Always safe when used as directed — no risk of oxygen depletion or fish stress.

British Made – HouseProud Pond Algae Clear is formulated and manufactured in the UK with over 50 years of product development expertise behind it. Part of the trusted HouseProud Home & Garden range, it is designed to handle green water treatment, sludge and organic waste, algae and blanket weed, and routine pond maintenance in a single easy-to-use product. Bring your pond back to life the natural way.

How to use:
Remove cap & foil seal. Shake well before use. Fill a watering can or bucket with pond water and add 20ml per 1000 litres (220 gallons) of Pond Algae Clear. Stir thoroughly and add evenly around the pond.

Crystal Clear Pond & Lake Water

Green water, blanket weed, sludge build-up — most pond problems come back to the same thing: too many nutrients in the water. HouseProud Year-Round Pond Algae Clear tackles that root cause with a concentrated blend of beneficial living bacteria that actively digests organic waste, starves algae of its food source, and keeps your pond clearer with far less effort.

Unlike copper-based algaecides that kill algae temporarily but leave the underlying nutrient load untouched, this treatment breaks down the decaying leaves, fish waste, and organic sludge that fuel the problem in the first place. The result is genuinely clearer water, a healthier ecosystem for your fish and plants, and a pond that stays balanced — not one that needs constant retreating.

What It Treats

Green water and suspended algae. Blanket weed. Bottom sludge and organic waste build-up. Excess nutrient levels caused by decaying plant matter and fish waste. One product handles the lot.

Why It Works Differently

The concentrated beneficial bacteria in this formula don't just mask the problem — they consume it. By digesting the organic waste that sits on the bottom of your pond and breaking down the nutrients dissolved in the water, the bacteria remove the conditions algae needs to thrive. Over time, you'll see clearer water, reduced sludge, and a pond that's far easier to maintain.

Works Year-Round — Down to 4°C

Most biological pond treatments stop working when temperatures drop. This formula stays active down to 4°C, so your pond continues to be protected through autumn and winter when falling leaves and organic debris are at their worst. No seasonal gaps, no switching products.

Safe for Fish and Wildlife

Completely safe for all pond fish including koi and goldfish, aquatic plants, and visiting wildlife such as frogs, newts, and birds. Suitable for ponds with or without filtration systems.
