Aquaculture water treatment chemicals for Australia

Clarifiers, conditioners, minerals and oxygen for prawn, barramundi and finfish — nine products mapped to the cycle you already run, from dry-out to discharge. For pond and tank water only, never for feed.

The pond-water range

Nine products, ordered by the pond cycle — dry-out, fill, stocking, grow-out, bottom and discharge. Each page carries the specification, key advantages and a dosage table in both hectares and acres.

The biological range

Sludge, the nitrogen cycle and persistent H₂S are biology. That half of the Kelvin Bio Organics catalogue is under Australian import permit application — register interest and it moves up the queue.

Where we supply

Aquaculture chemicals, Australia-wide

We supply from East Perth, Western Australia, to farms and hatcheries across the country. Australian aquaculture is concentrated in a handful of regions, and the water chemistry differs in each — bore-fed inland ponds behave nothing like a coastal marine system, so we set rates against your water test rather than a national average.

Queensland

Prawn and barramundi farming from the Gold Coast to Cairns — warm-water ponds where oxygen and bottom sludge move fastest.

Northern Territory

Barramundi and prawn operations around Darwin and the Top End, on tidal and marine intake water.

Western Australia

Our home state — Kimberley and Pilbara marine projects, plus inland and bore-fed systems where potassium and magnesium run short.

NSW · VIC · SA · TAS

Freshwater finfish, yabby and trout operations, and land-based recirculating systems in cooler water.

Common questions
Are Kelvin Care Aqua products added to feed?

No. Every product in this range is for pond and tank water treatment only, and is never added to or mixed with feed. Claims are limited to water-quality parameters.

Which pond clarifier works in seawater?

AQUA CLEAR works across the full salinity range, from freshwater grow-out to marine prawn ponds, because it combines calcium bentonite sweep flocculation with a cationic bridging polymer rather than relying on salinity-sensitive charge neutralisation alone.

Do these products contain live microorganisms?

No. All nine products in this range are mineral, enzyme or chemical formulations. Our biological range is listed separately and is under Australian import permit application.

How do I know what dose to use?

Every product page carries a dosage table with both per-hectare and per-acre figures. For AQUA ION and BIND FE, dose against a measured water test rather than an estimate — send us your analysis and we will calculate it.

Where are the products manufactured?

In Chennai, India, by Kelvin Bio Organics, which has made aquaculture and leather process chemistry since 1993. Kelvin Care Australia is the authorised Australian distributor.
