The fast-growing micro-organisms in Hydra Bio Start rapidly establishes an effective biomass. This product also boosts the activity of any existing biomass. Improves the efficiency of large or small sewage plants.

Ideal for use as a start-up treatment product, to ensure fast and proper break-down of organic material.

Clears up accumulated blockages and prevents formation of blinding screens. Bad odour and flies are controlled as a result of clear, fast flowing and suitably treated waste.

Extensive metabolic capability with high emulsification properties.

Contains multiple bacillus strains, helps reduce dangerous pathogens such as cholera, typhoid etc in septic tanks and bio treatment plants.

RAW SEWAGE ON GROUND                                                                                                 

Simply sprinkle Hydra Bio Start over the contaminated area. Due to its rapid oxygen release, when applied like this, Hydra Bio Start acts as a disinfectant rapidly killing harmful pathogens.


By using Hydra Bio Start on commissioning the plant, the microbial population will rapidly colonise the system (results are seen within 48 hours). This enables the system to work faster and more effectively.

Dilution Rate

Use 1 kg/m³ of Hydra Bio Start in the primary tank of size 1m³ to 5m³.

Use 0.75 kg/m³ of Hydra Bio Start for the tank size of 10m³+.

Add Hydra Bio Start into the primary tank. Higher temperatures, but not exceeding 45ºC enhance the performance of the product. At lower temperatures, the bacteria do not die off although the speed of organic waste degradation may slow down.

Keep out of reach of children. Risk of serious damage to eyes. Avoid contact with eyes. In case of contact with eyes, rinse immediately with plenty of water and seek immediate medical advice. Harmful if swallowed. Contains naturally occurring non-pathogenic bacterial cultures. Wash hands after use and avoid drinking water and foodstuffs.

Annual Purchase
02 September 2020  | 

This is my annual purchase to restart my septic tank after it has been emptied.

The tank is a modern three compartment system with the centre compartment being aerated.

It is recommended to be emptied every six months as it discharges into a river; however we are able to do it annually by using your products.

Bad Smell Rectified
11 October 2019  | 

I had a very bad smell coming from my septic tank, I think the wife went crazy with the bleach. Dosed the system with Hydra Bio Start and after a week the system is smelling sweet.

I was not sure if this product would work, as I have been having issues for years with my system. However after a couple of weeks I could tell that the solid fat surface was breaking up, and the bad smells had gone.

I had bad odours from my septic tank and the Bio Start worked it out. We use the occasional bleach and other cleaning products so adding this brings back the good bacteria needed. Excellent product.
