Artificial ponds are influenced by many environmental factors Pond water is more than just clean water. Oxygen, carbon dioxide, nutrients, and many other elements make it into living water and thus a habitat for plants and animals. However, many ponds are often too small for the fish stock; acid rain, sun, and leaves, or other organic pollution over-stress the pond. The requisite balance is restored and supported with OASE aqua active.

OASE aqua activ Quickstick Water analysis - fast, simple, and safe (even for beginners). Determine the 5 most important water values.	OASE aqua activ Test-Set User-friendly set with measuring cup, measuring spoon, colour control table and four different solutions for accurate and simple measuring of pH value, carbonate hardness, total hardness and nitrite content. The OASE aqua activ Test set Plus enables simple and dependable determination of nitrate, phosphate and Ammonium/ammonia content of your pond.
OASE aqua activ - String algae control Works safely against string algae. Not harmful to fish and other pond dwellers. With enzymes, trace elements, and living microorganisms. Dead algae is broken down biologically, the balance in the pond is stabilised. Important: ensure adequate oxygen supply through water circulation!	OASE aqua activ - Starter Bacteria Prepares the pond water for fish by adding vital active microorganisms. Biological self-cleaner.

Important: ensure good aeration through water movement. Optimal supplement: Oxygen Stabiliser	OASE aqua activ - Oxygen Stabiliser Works from the pond floor upwards and thus prevents formation of gas, which can be hazardous to living organisms. Supports the organic self-cleaning properties of the water. Reduces the formation of algae and slime and neutralises toxic waste products. First aid for oxygen deficiency.
OASE aqua activ - pH Value Minus Natural agent for reducing the pH value. First aid for excessively high pH values, prevents ammonia poisoning. Important: Make sure the KH value is sufficient! Optimal supplement: Biostable Regulator	OASE aqua activ - Hardness Plus Increases the carbonate hardness level in the pond water. Treats soft tap water or rain water for filling. Stabilizes the calcium/ carbonic acid balance, which also determines the pH-value.
OASE aqua activ Crystal clear instant Clarifies murky water (particularly in the case of algae bloom). Does not harm plants and animals. It is effective against the finest pollutants as well as phosphates and heavy metal compounds. The flocculation that results can be removed with the Pondovac pond vacuum or with a net. Important: ensure good water circulation! Optimal supplement: Hardness Plus, Oxygen Stabiliser and pH-Value minus	OASE aqua activ Vital 3 Pond Vitamin Contains vitamins, minerals and trace elements for promoting fish health as well as nutrients for regulating the filtering biology and water quality. Stabilizes the pH value and the oxygen content of the pond.
