Pond bacteria for biological balance

Simon van der Velde (pond specialist and aquatic plant grower since 1986) does not do water testing, and has already built thousands of ponds without the use of expensive pumps, filters and water improvers such as GH plus. After all, we don't do this in nature either.

In now more than 35 years Simon has built thousands of ponds in a natural way. In a natural pond without liner you can easily achieve clear biological equilibrium with only hardy pond plants. For a pond with pond liner or a pond container, only 2 additional things are needed, namely: 1. pond substrate (pond bottom to which bacteria can attach) and 2. The proper pond bacteria.

Why Bacta Clear pond bacteria?

There are now hundreds of different types of bacteria on the Internet, leaving many unsure which are now the right bacteria for the pond. Simon found a solution to the hundreds of different bacteria found on the Internet. He developed his own pond bacteria that contains not one, but two different types of bacteria needed to balance the pond. You no longer need additional products and save on the annual cost of unnecessary water testing.Best of all, Bacta Clear is 100% environmentally friendly and not harmful to humans, plants or animals.

How often to add bacteria in the pond?

Adding is easy, just 2 times a year:one inthe spring (March/April) and once in the fall (late August/September)

How do I use Bacta Clear?

Pour 1 bottle of Bacta Clear (good for up to 20,000 liters of water) directly into the pond. After opening the bottle, the bacteria have a limited shelf life. It is best to empty the entire bottle into the water at once, even if you only have a small pond or a mini pond.

Effect of Bacta Clear bacteria

Pond bacteria ensure clear water and better growth of aquatic plants. Excess fish food, droppings, rotting leaves and dead algae cause a dirty layer of debris in the form of goo and sludge at the bottom of your pond. Bacta Clear contains the right bacteria and enzymes that will "eat" your dirty bottom layer. Use 1 liter from 1,000 liters of water up to a maximum of 20,000 liters of water.
