Pond Water Treatment & Algae Clear Year-Round Natural Bacteria Formula, Clears Green Water, Sludge, Fish Plant Safe HouseProud 1L Treats 50,000 Litres

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 IN EVERY SEASON – 4°C WINTERS TO SUMMER HEATWAVES – The specially formulated living bacteria blend stays active in water as cold as 4°C, so you can treat through autumn and winter when sludge and organic waste build up. In hot, sunny spells it's normal pond biology for algae to grow at its seasonal peak — faster than any natural treatment can digest the nutrients feeding it — and warm water holds less of the dissolved oxygen the bacteria need to work. In summer, simply double the dose to 40ml per 1,000 litres, boost oxygen with a fountain, waterfall or air pump, and shade part of the surface with floating plants. Keep dosing weekly and clarity returns as the bacteria catch up. NATURAL BACTERIA FORMULA – TACKLES ALGAE AND SLUDGE TOGETHER – 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.
