Colombo Mineral 1L pH Min Pond Water Treatment Level Reducer Stabiliser Quick Adjuster Control Lower Down Decrease Garden Fish Koi Safe Description
High pH levels in ponds can be dangerous to fish and wildlife within. Colombo pH Min is an effective and safe pH reducer, adjuster and water stabiliser designed to lower and control alkaline conditions safely. It works to bring down pH levels into the optimal range of 7-8, helping to create a healthier and more balanced aquatic environment.
Colombo pH Min works by providing a gradual decrease in the pH without causing sudden fluctuations that can shock fish. Its quick action allows for safe correction of water conditions while maintaining biological stability within the pond ecosystem.
Things that can cause a high pH in garden ponds include algae blooms, high KH levels, concrete and mineral leaching, high pH source water and the time of day. It is recommended to test your water weekly during the spring/summer. Doing it weekly ensures water stability for optimal fish and pond health.
Before Use: Test your water and ensure the KH is at least 6DH.
Dosage: Use 50ml of treatment per 1,000L of pond water. If needed, continue dosing daily until the levels are correct. Do not use more than 50ml daily.
