PHYTOstabil is a salt mixture specially produced for seawater aquaristics, which provides optimal provides culture conditions for marine phytoplankton (micro suspension algae).

The microalgae in PHYTOstabil containing plant nutrients nitrogen (as nitrate), phosphorus (as phosphate) and iron are standardized according to the standard used in scientific and industrial phytoplankton breeding used "Enriched Seawater Medium f/2".  Furthermore PHYTOstabil supplies your phytoplankton culture with important trace elements such as manganese, molybdenum, and copper, as well as vitamins and selected amino acids, which phytoplankton algae for fast and healthy growth.

Since the main nutritional elements nitrogen, phosphorus and iron are present in a ratio, the cultivated algae continuously consume these nutrients. This ensures (in contrast to the flower fertilizer) that only small amounts of nitrate and phosphate remain in the culture medium. Correspondingly, with optimal phytoplankton density in the culture vessel, the medium can be used to feed azooxanthellate corals and other filtering agents (e.g. sponges, hairy stars, sea squirts) directly can be dosed into the aquarium, without the phosphate content in the saltwater aquarium in particular is rising uncontrollably.

Of course PHYTOstabil is also suitable for the culture of phytoplankton (such as Nanochloropsis marina) as basic food for zooplankton (such as the rotifarian Brachionus plicatilis), which in turn is used in the fish farming is applied.

Since ready-mixed culture media in liquid form require high sterility requirements in order to prevent the undesired growth of bacteria and fungi in opened bottles, is PHYTOstabil was developed as a salt mixture. Therefore, adapted to the individual fresh culture medium can be prepared at any time. This enables the following with opened packs a significantly longer shelf life than with ready-made culture media.
