25 Kilo bag = £59.50 incl vat
Aquaplancton works on the pond’s surface area not depth of water or gallon capacity. To work this out, your approximate length x width = your surface area. It doesn’t need to be exact as you can’t overdose with Aquaplancton.
Large Ponds: Buy the 25 kilo bag which will treat up to 50 sq metres (500sq ft).
e.g. 10ft x 8ft = 80sq ft., so use 8-lbs.
