Aquazoi Sludge Clean

Aquazoi Sludge Clean

Aquazoi Sludge Clean is a high-potency bacterial concentrate that controls the solid waste and organic sludge that build up in ponds, lakes and aquaculture systems. It is made for South African koi and goldfish keepers, water-feature owners, hatchery operators and anyone managing larger bodies of water who wants a natural way to tackle muck on the bottom. The formula is 100% natural, non-toxic and biodegradable, and it contains no chemicals.

Key Benefits

• Dissolves organic sludge: the concentrated bacteria break down accumulated solid waste in ponds, lakes and aquaculture environments.
• Breaks down dead algae: helps clear decaying algae before it adds to the layer of sludge on the bottom.
• Helps reduce disease-causing organisms: less decaying organic matter leaves a cleaner environment for fish.
• Supports faster fish growth: according to the manufacturer, it promotes faster growth in fish.
• Active under 12°C: the bacteria keep working in cooler water, which is useful through chilly winters on the Highveld and in other colder regions of South Africa.
• Chemical-free formula: contains no chemicals and is 100% natural, non-toxic and biodegradable.
• Safe for the whole system: harmless to pipes, humans, birds, fish and plant life, so it can be used around planted ponds and in areas wildlife visits.
• Long shelf life: 24-month shelf life, so you can keep stock on hand for follow-up treatments.

How to Use

• Add Sludge Clean directly to the water. It does not need to be diluted.
• Dose continuously, either by batch treatment (adding a measured amount by hand) or through an automated dosing system.
• Repeat dosing as needed. The number of doses depends on how severe the sludge build-up is, so heavily silted ponds may need several applications.

Dosage

1 litre of Sludgeclean treats 30,000 litres of water. Work out your pond or tank volume first, then dose at this rate. Add further doses as needed for heavy accumulations of solid waste.
