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.
Different sizes, suitable respectively for 60 / 100 / 180 / 250 / 400 / 500 l pools with denser than average planting or stronger lighting (up to 0.4 W/l). If the lighting is stronger, it may be necessary to use the next package size up of KramerDrak Power.
Using KramerDrak Power is an easy and reliable way of avoiding competition between difficult and sensitive aquatic plants. Because the nutrients are almost continuously available, no plant is any longer in a position to “snatch away” nutrients to another's disadvantage, i.e. consume them faster than its rivals.
- The release of nutrients corresponds to the recommended dose of KramerDrak special fertilizer in a pool of the same size
- Release Time: 2 Months
- Storing the closed containers in a dark place: unlimited
- Place in the filter or another location with good water through-put. Before the first usage flush through well using fresh water
- For larger pools, simply use more than one plastic mesh-bag
- Vor der ersten Verwendung kurz mit fließendem Wasser abspülen
The application can be stopped at any time by simply removing the plastic mesh-bag from the water (but please be careful because the fertilizer solution contains heavy metal components, like iron and manganese that can cause difficult to remove marks and so please use an insensitive underlay).
After large water exchanges and/or in pools with a very large requirement for fertilizer it is a good idea to fertilize the fresh water with half the recommended dose of Ferrdrakon or Ferrdrakon K (when a larger need for potassium exists). It serves then as a replacement for the fertilizer lost when exchanging the water.
Aquarium plant fertilizers, water conditioners, remineralizing salts and supplies for marine aquaristics made by a specialist. Dr. Andreas Kremser (DRAK) offers a wide product range for planted aquarium enthusiasts and aquascpapes. Besides micronutrient fertilizers like his Ferrdrakon complete iron fertilizer, he offers macronutrients as well as micronutrient fertilizers for special purposes like the KramerDrak - complete iron fertilizer for strongly lit tanks.
