Phosphate Supplement Fertilizer - Long-term fertilizer - continual addition of phosphate
Some intensively planted and lighted pools with a moderate till low fish population need, in comparison to the majority of typical aquariums, a supplement to the basic food stuff phosphorus - P resp. phosphate - PO4.
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.
The desired value ranges between 0.1 - 0.2 mg/l phosphate. More than that is seldom necessary and usually only promotes algae growth unnecessarily.
When changing the water, it is a good idea to fertilize the fresh water with Eudrakon P solution. This will compensate for the phosphate removed with the water change.
Using Eudrakon P 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.
Adsorber materials, which are offered for silica binding (SiO₂), always bind more or less phosphate!
If you want to permanently increase the phosphate content of your aquarium water, you have no choice but to remove such silicate adsorbers from the water cycle.
