About this product
This 500ml treatment rapidly clears green 'pea soup' pond water by making suspended algae particles bind together into larger, heavier particles that sink to the bottom. The settled particles can then be removed via filtration or sludge treatment. It works quickly and is safe for all pond inhabitants.
Used for
- Garden ponds with green water caused by suspended algae
- Koi ponds requiring rapid water clarity restoration
- Pre-treatment before sludge removal systems
- Short-term algae control in established pond ecosystems
