How should this be used if pond alkalinity is very high?

For first-time use, apply 1 liter per 8-10 mu of water and repeat after 3 days; the dose can be increased for severely alkaline conditions.

Can this product be mixed directly into feed?

Yes, mix 80-160ml into 40kg of feed and feed for 5-7 consecutive days; periodic use gives the best results.

Should dosage be increased during heavy blue-green algae blooms?

Yes. The standard dose is 1 liter per 10 mu, repeated 1-2 times on alternate days, with a higher dose during heavy blooms.

Core Specifications

Main Ingredients	Bacillus subtilis, Rhodopseudomonas palustris; carrier: purified water and others.
Dosage & Usage	For first-time use to lower pond alkalinity, apply 1 liter per 8-10 mu of water, repeating after 3 days at 1 liter per 10-15 mu; increase dosage in severely alkaline water. To reduce blue-green algae blooms, apply 1 liter per 10 mu, repeating 1-2 times on alternate days, with higher doses during heavy blooms. For reservoirs or large water bodies, use 1 liter per 10-15 mu, adjusting for water quality. As a feed additive, mix 80-160ml into 40kg of feed and feed for 5-7 days, with periodic use for best results.
Packaging Spec	5 liters per drum.
Storage Condition	Store sealed in a cool, dry, well-ventilated place, away from direct sunlight.
Shelf Life	24 months

The synergy of Bacillus subtilis and photosynthetic bacteria detoxifies and deodorizes quickly, degrades ammonia, nitrite and hydrogen sulfide, and keeps algae fresh and stable long-term - while doubling as a feed additive for nutritional support in aged black, green or foul-smelling ponds.

Key Selling Points

Water Purification

Detoxifies and deodorizes, accelerating oxidative breakdown of leftover feed and waste on the pond floor.

Ammonia & Nitrite Reduction

Lowers nitrite, ammonia and hydrogen sulfide levels in the water.

Algae Stabilization

Improves aged black or green water and algae crashes, keeping water color fresh over time.

Nutritional Feed Additive

Can be mixed directly into feed as a nutritional supplement to improve feed efficiency.

The product purifies water, reduces water viscosity, lowers organic matter content, raises dissolved oxygen and improves the pond environment. It is highly effective against aged black or green water, algae crashes, foul odor, excess foam and suspended matter, keeping the algae balance fresh, active and clear over the long term.
