Solutions
Pool pH Control
The solution to green water starts with pH, not blindly adding more disinfectant.
Test, read, adjust, circulate, test again. That’s the product: a method, not a magic bucket.
Minimum Kit
3-in-1 or 7-in-1 test strips, pH− if you usually run high (common), pH+ in case rain brings it down. Granules for medium-sized pools; liquid for 5-20 L if you correct often.
Order
pH → alkalinity if it fluctuates → chlorine. Never the other way around by habit.
What We Recommend at Control Garden
Pool test strips and solid or liquid pH+ / pH− ranges. Measure twice a week in season.

Green Water in the Pool and pH?
Adjust pH, filter, and then disinfect. Chlorine bucket at pH 8.2 is a waste.
