Clear water step 1/2:

Factor size

The size of your pond and the volume of water will determine the number of fish and plants you can
comfortably stock.

  • The general rule is that you need a minimum of 3,000 litres of water in your pond to keep fish.
  • For every 1,000 litres of water, you can stock a maximum of 2-3, 8cm long fish but if you keep the smaller sunbleaks, you can increase this to 7 fish per 1,000 litres. Remember: your fish will grow significantly until they reach their adult size, at which point their spatial needs will also increase. 
  • It’s a paradox but true: A low number of plants (especially when you are keeping fish in the pond) can lead to heavy clouding of the water due to algae, therefore, structured planting is essential for the biological balance of the pond and beautiful, clear water. You can also get cloudy water if there are too many plants or plant cuttings have not been removed from the pond. The general rule is: Two third of the pond surface should be planted.
