High-count Bacillus subtilis breaks down organic matter and reduces pathogens in the pond, builds good water colour and the natural food chain — helping fish ponds turn green and holding back toxic gases such as ammonia, nitrite and hydrogen sulfide.

3 main benefits
- 01
Supplies beneficial microbes that break down organic matter and reduce pathogens in the pond.
- 02
Builds good water colour and boosts the natural food chain in the pond.
- 03
Handles and prevents toxic gases such as ammonia, nitrite, nitrate and hydrogen sulfide.
Building water colour and shifting to green algae in fish ponds
New water takes on diatom (tea-coloured) algae more easily than green algae, so the job has two stages: SOILMAX builds the tea colour first, then NIAZYME gradually shifts the pond to green algae — the colour fish ponds favour because green algae are more nutritious. Routine as taught by Thần Vương technical staff, with doses from the product labels.
- 01
Prepare the water
Fill, disinfect and wait about 48 hours before seeding microbes. Well water: after disinfection, use PREMIX EDTA to remove acidity (phèn), iron and heavy metals.
- 02
Build tea colour with SOILMAX
Aerate 1 pack of SOILMAX with 1 kg of FYTO FLOC (or molasses) for about 2 hours and spread at 9 – 10 am, 1 pack per 2,000 – 2,500 m³. Repeat after 3 – 5 days; about 2 rounds usually bring the water to tea (diatom) colour.
- 03
Fingerlings: keep the tea colour
Stock the fish and feed normally — fish waste feeds the algae. Fry-to-fingerling ponds usually keep tea colour for about the first 30 days.
- 04
Shift to green algae with NIAZYME
Soak NIAZYME with FYTO FLOC (or molasses) and aerate 4 – 5 hours, then spread at 9 – 10 am, 1 kg per 8,000 m³. Repeat every 4 – 5 days; after 2 – 3 applications the water gradually turns from tea to green.
- 05
Grow-out fish: keep it green until harvest
From here on, use only NIAZYME routinely, 1 kg per 10,000 m³ — no more SOILMAX.
- 06
When to bring SOILMAX back
Green algae too thick, high toxic gases or a lot of blue-green algae: stop NIAZYME and use SOILMAX at 1 pack per 1,000 m³ for 2 – 3 days in a row.
Tea colour lasts longer, green colour feeds better
Tea colour (diatoms) is more stable, so shrimp hatcheries usually keep tea-coloured water. Fish ponds usually run green from fingerling to market size because green algae are more nutritious — at the cost of watching that the colour does not get too dark.

FAQFrequently asked questions
- What is NIAZYME used for?
- Probiotic that builds water colour and turns fish pond water green
- How to use NIAZYME?
- Recommended doses: Pond renovation: 1 kg/8,000 m3 of water, applied as soon as the water level is full to raise microbial density, stabilise and build water colour. Pond just desludged, cloudy or flocculent water: 1 kg/10,000 m3, applied after the water change to break down organic matter and stabilise water parameters. Fingerling ponds that are hard to exchange with a sludgy bottom: 1 kg/8,000 m3, 2 - 3 days in a row, to neutralise toxic gases and improve the water. Routine: 1 kg/10,000 m3, keeps pond water stable and raises beneficial microbes. Note: Best applied at 9 - 10 am. Soak with molasses and aerate for 4 - 5 hours before spreading for best results. Adjust the dose to actual pond conditions, stocking density and animal health. Seal and zip the bag right after use if not finished.
