Long-term fertilizer / Full iron fertilizer - Automatical Daily Fertilizing

According to the size of the aquarium the fertilizer reserve consists of a hand-full of material, ready for application and packaged in a plastic mesh-bag. The material system (Aquafim^®) itself is non soluble and does not give-up any undesired substances into the water. Once in usage, day after day a measured amount of fertilizer is released. Through this constant steady release there is no so-called “increased step of concentration”, what has a positive effect on both plants and animals - and all that without having to purchase an expensive and sensitive electro-mechanical dosage pump.

Period of use: 3 months

Suitable for 150 - 210 l pools with average planting.
For bigger water tanks, please use more net packs.

In water tanks with a high demand for fertilizing, it is advisable to add to the fresh water after bigger water exchanges, some Ferrdrakon or Ferrdrakon K as far as there is a special need for potassium. Then it also serves as a substitute for the fertilizer lost when changing the water.

Place it in the filter or at another well streamed area.
Please rinse with running water before first use.

The use can always be stopped by removing the net pack out of the water (please note that while drying, fertilizer solutions may cause constant stains due to their heavy metal content, such as iron and manganese. Please use a robust pad).

New: Each package now includes a removable, waterproof label (writable with a permanent marker or foil pen) for noting down the date of the next exchange of the fertilizer net bags.
