      Koi pond construction and maintenance

      A koi pond is a wonderful addition to any garden. Not only does it provide a soothing place to relax and enjoy nature, but it is also the perfect home for colorful koi fish

      Water hardness and your pond, what is the optimal GH (dH) value for best water quality?

      Natural ponds are beautiful and relaxing additions to your outdoor space. It is important to take proper care of your pond and its inhabitants, and water hardness is an important factor in this regard

      Wie hält man einen Teich bei Winterfrost offen?

      A small garden pond can freeze over after a night of hard frost. If you do nothing, the fish get into trouble. Harmful gases, from decaying plant debris, cannot escape from the pond and oxygen cannot get in.

      How to prevent green pond water in a koi pond?

      Green pond water can spoil the appearance of your koi pond and disrupt the habitat for your fish.
