PondFerr – a fertilizer for aquatic plants with iron that creates favorable conditions for the development of plants, fish, and filtration bacteria in ornamental and other types of ponds. It the provides bio-elements essential for life in the form of easily digestible compounds: potassium, magnesium, iron, cobalt, copper, zinc, manganese, boron, iodine, vanadium, fluorine, selenium, nickel, molybdenum, and lithium. It does not contain phosphorus and nitrogen, and therefore does not promote algae blooms. This mixture has a positive effect on the growth and color of aquatic plants. It counteracts the effects of a critical lack of nutrients, such as: the edges and tips of leaves yellowing and dying, weak inflorescence, lack of flowering, and faded colors. Safe for people, animals, and the environment.

How and when to use this product – calendar with application dates


When establishing a swimming pond or a new pond, most often tap water is used. Tap water usually doesn’t contain sufficient amounts of certain nutrients required by plants.

In swimming ponds, in order to limit the development of thread algae, nutrients, including micronutrients needed by beneficial plants, are limited.

Plants in nutrient-poor water stop growing, and, after a while, they begin to die.

PondFerr counteracts the critical effects of nutrient poor water such as: yellowing and dying of the edges and tips of the leaves, poor inflorescence, lack of flowering, and faded colors.

PondFerr adds all the bio-elements necessary for life to water (even “hard” water) in the form of non-toxic compounds which are easily absorbed by plants and fish.
