Clarity and Clarity PRO - A healthy pond is a clear pond. A healthy pond is a complex environment where fish, plants and other animals live in balance. Sometimes this balance is disturbed. Often this happens in the spring and summer as the pond warms up resulting in algae and blanket weed growth.
Keep your pond clear and healthy by adding Clarity or Clarity PRO (depending on the size of your pond).

Clarity is supplied as a powder and is simply added to the pond between March and Septmeber. It is a natural blend of bacteria normally present in healthy ponds. By adding Clarity to your pond, these bacteria will clean the pond controlling blanket weed / algae, reduce organic debris, reduce ammonia / nitrates / phosphorous and reduce pond scum / odour in stagnant waters. Supplied in 500g tubs, which will treat ponds up to 500 litres for 6 months.
"Hi Jon, I just wanted to let you know that the Clarity pond stuff I got from you is absolutely amazing. It cleared our wildlife pond of algae and slime within two weeks, after six years of battling the dratted stuff with barley straw and a net! Feel free to quote me if you like!" Thanks again Kate
Clarity PRO - Got a much larger pond? Clarity PRO is a much more concentrated form of Clarity for use in larger ponds i.e. over 549 gallons (2500 litres) although any size of pond or lake can be treated.

Clarity PRO - For ponds up to 4500 gallons or 20,000 litres add 62.5g initially, then 2 weeks later add 37.5g, then 2 weeks later add 25g. Repeat dose at monthly intervals. A 25g scoop is supplied. For a pond half the size, use half the amount. Treating a pond of this size, 1 kg of Clarity PRO will last 3 years! making it great value for money. Clarity Pro is supplied as a powder and is dissolved in luke warm water. Allow to stand for 4 hours, with occasional stirring to encourage bacterial activity. Simply add this solution to your pond making application of Clarity Pro very easy.
Clarity PRO Calculation - To work out how much Clarity PRO is needed for a LARGER pond a simple formulae is used :-
Pond Length (m's) x width (m's) x depth (this is average depth in m's) = ? then divide this figure by 1.6 and this is the dose factor in grammes.
i.e. My pond on the land is 10m x 10m x 2m deep, therefore my dose factor is 125g (10 x 10 x 2 /2 = 125)
Clarity PRO Treatment - An initial treatment of 2 x dose factor i.e. in my case 2 x 125g = 250g, followed by a second dose of 1 x dose factor i.e. in my case 125g 2 weeks later and then 1 x dose factor every month after that. Therefore 1kg of Clarity Pro will last me 5 months.
N.B. Clarity Pro has been used successfully on amenity ponds and lakes to clear blanket weed and algae matting. For advise on Clarity Pro or help with the formulae, please email dimensions of pond to jon@greengardener.co.uk including depth and I will work out treatments.
