Tetra Pond AlgoFin*

Algae occurs wherever water is found – even if the water is only a temporary presence. It does not become visible until it gets out of control, and may cause problems. Algae can proliferate very quickly in favourable conditions, grow over everything else and negatively impact the water parameters. To prevent algae, the first thing you need to do is stop conditions from developing that encourage algae growth:

1) Avoid and/or limit intense light from the sun or lighting by choosing a suitable, shaded location for the pond. Another useful tip is to include floating plants such as water lilies that also reduce the incidence of sunlight.
 
2) Reduce high nitrate and phosphate levels or prevent high levels from occurring using fast-growing pond and marsh plants. The plants absorb nitrate and phosphate as nutrients before excess nitrate and phosphate enable algae to grow.

3) Remove built-up sediment and other dead organic material from the water at an early stage.

4) Avoid overfeeding the fish in the pond.

Blanketweed is a sign of good water quality combined with excessive light penetration. You can reduce light penetration in a totally natural way by adding and specifically fertilising floating plants such as hornwort or water lettuce. You can also effectively treat blanketweed with Tetra Pond AlgoFin followed by Tetra Pond AlgoClean.

Reduce light penetration and excessive nitrate and phosphate levels. The incidence of light can be reduced with water lilies or floating plants (hornwort, water lettuce), for example. Also make sure to feed your fish moderate quantities of food with low nutrient input levels. We recommend Tetra Pond AlgoRem to specifically target floating algae.

Blue-green algae means that your pond does not have the right biological balance. Make sure that your pond is sufficiently aerated, give your fish a moderate amount of food and remove sources of decay (caused by fish waste and dead plant material). We also recommend changing the water and adding filter bacteria such as Tetra Pond FilterStart. You should also clean your filter regularly.
To combat blue-green algae specifically, we recommend using Tetra Pond AlgoFin and Tetra Pond AlgoClean.

To prevent algae, the first thing you need to do – early in the year – is stop conditions from developing that encourage algae growth:

1) Avoid and/or limit intense light from the sun or lighting by choosing a suitable, shaded location for the pond. Another useful tip is to include floating plants such as water lilies that also reduce the incidence of sunlight.
 
2) Reduce high nitrate and phosphate levels or prevent high levels from occurring using fast-growing pond and marsh plants. The plants absorb nitrate and phosphate as nutrients before excess nitrate and phosphate enable algae to grow.

Green water indicates that floating algae is probably just starting to grow. We recommend using Tetra Pond AlgoRem to specifically inhibit its growth.

Tetra Pond AlgoFin combats all forms of algae – particularly blanketweed, but also green algae, floating algae and smear algae.
