Pond Balance safely and gradually adjusts the pond water chemistry, achieving a balance which effectively clears blanket weed whilst promoting plant growth. Pond Balance solves your blanket weed problems without the effort involved in manual removal or the inherent risk of killing your valuable plants and fish which is associated with pond algaecides. For long-term effectiveness, usage should begin from early Spring and continued regularly during the warmer months. For best and consistent results this treatment should begin with a repeated dose, once every 10 days for the first month, and once per month thereafter, or more frequently, as required. Please see our Dosage Calculator for your exact dosing requirements.
