Application and Dosage
Application
Use after water changes, filter cleanings, or when conditioning new ponds.
Dosage
Before use, check the carbonate hardness (KH) of the water, as a stable value of 6-10° dH is essential for safe pH regulation. Distribute Colombo pH- evenly throughout the pond, ideally in areas with good water circulation. Dissolve the product in a bucket of pond water beforehand and then slowly add it to the pond. The filter system should be running during application to ensure even distribution. After dosing, check the pH level regularly and add more if necessary to maintain stable water quality.
