SANGOKAI water additives
Having success with your ocean at home
SANGOKAI water additives.
Effective products for your reef aquarium.
SANGOKAI is specialised in the supply of tropical marine aquaria with nutrients and sea water components. We possess fifteen years experience in developing unique organic nutrient combinations based on a high level of academic knowledge of tropical coral ecophysiology and a huge experience in professional reef keeping. The longterm positive results of our specific and continuous organic nutrient supplementation is demonstrated and reproduced in our many customer tanks in Germany since our foundation in 2012.
SANGOKAI products are not only exclusive on the market and are independently developed, manufactured and controlled in our production facility in Northern Germany. In fact, the functional ecological principles behind our products derive from academic knowledge in tropical marine biology, dive experience and live observations, as well as scientific investigations in the natural coral reef environment.
Thus, by using SANGOKAI products you are not only taking care of your corals, but you are improving the ecological productivity of the entire aquarium system, creating longterm stability in the aquarium biology and maintaining a constant and healthy seawater environment.

SANGOKAI is a specialist in reef aquarium nutrition
SANGOKAI offers a product range which also includes a selection of effective filter media as important tools in reef keeping from a general point of view. However, the core products are water additives and supplements which can functionally be divided into two groups: seawater composition and lime-element balance (LEB), and – most importantly – inorganic and organic nutrient supply.
While the stabilisation of the seawater composition and LEB is a crucial practical task in reef keeping to allow for a healthy marine environment, the SANGOKAI organic nutrient additives represent the heart of SANGOKAI reef keeping. It follows fundamental biological principles what makes SANGOKAI not only a natural product, but also a comprehensive way to generate and maintain a healthy reef environment, high biodiversity and longterm success.
Basically, in SANGOKAI reef keeping the nutrient balance is functionally separated from the lime-element balance (LEB). You can freely decide wether you want to choose a calcium reactor for LEB, or a supplement-based method like SANGOKAI BALANCE. The BALANCE product system exclusively deals with the stabilisation of the lime-element balance (Ca/Mg/Sr, alkalinity) and the long-term optimisation of the seawater composition. It does not supply nutrients.
By applying the SANGOKAI nutrient product systems you will provide the exact same organic nutrient level in any reef aquarium, whether you run a soft coral aquarium with a low calcium and alkalinity consumption, a small nano cube with Zoanthus and LPS corals, or a high-end SPS reef tank showing a significant daily uptake of calcium and alkalinity. The SANGOKAI nutrient products will deliver a constant organic nutrient balance for any type of reef aquarium.
We will attend your journey in reef keeping with the SANGOKAI products at any stage of your ocean at home. From the very beginning with your newly set up reef aquarium and the START products, over the establishment of a healthy reef aquarium microbiology and full tank nutrition with the BASIS products, to the point of a more specific coral supply using the HED products.
You will always find the best fitting product system to cover the individual needs of your SANGOKAI reef aquarium.

SANGOKAI principles of function and effects
By using SANGOKAI you are not only taking care of your corals.
You will help your entire reef!
Dissolved nutrients are the key to success.
Crystal clear coral reef waters prove that particles and phytoplankton must be very low in quantity and at the same time of extremely small size.
The low particle density is matched by a high water flow and exchange through ocean currents and tides. Consequently, there are only few food particles at a time, which, however, are available for 24 hours and are probably to small for us to recognise.
These specific conditions cannot be simulated by using particulate foods, bred phytoplankton or bacteria. While doing this, food densities were too high at a time, fluctuations in the food availability too strong, and at least, phytoplankton and bacteria bred outside the aquarium would potentially die and build up polluting detritus.
The key to success in SANGOKAI reef keeping are dissolved organic nutrients. They develop microbial biofilms and a living microfauna community which has its origin in the reef aquarium and is staying alive to create a complex and high-quality food web.
SANGOKAI does not contain any compound, which is not part of natural coral reef water.

Your SANGOKAI reef aquarium is protected from harmful effects.
Von den natĂŒrlichen Gegebenheiten im tropischen Korallenriff leitet sich das SANGOKAI BASIS-System mit seiner MikronĂ€hrstoffdosierung ab. Diese grundlegende und umfangreiche NĂ€hrstoffversorgung ist fĂŒr jedes Riffaquarium geeignet und simuliert mit einer Vielzahl verschiedener gelöster organischer MikronĂ€hrstoffe die VerhĂ€ltnisse im Korallenriff. Du brauchst fĂŒr Dein SANGOKAI Riffaquarium mit zooxanthellaten Korallen keine weiteren Korallenfuttermittel, kein Phytoplankton, keine Bakteriensuspensionen oder Ă€hnliche Produkte.
Das BASIS-System ist ein autarkes System, das darauf abzielt, die FĂ€higkeit zur Eigenproduktion von Kleinstlebewesen und Plankton durch Dein Riffaquarium selbst auszubilden. Das macht es fĂŒr Dich nicht nur ĂŒbersichtlicher und praktisch einfacher, sondern Du gibst dem Aquarium nichts hinzu, was es nicht verarbeiten und damit schĂ€dlich belasten kann. SANGOKAI ist ein gesundes und v.a. biologisches Additiv-System, dass auf einem nachvollziehbaren ökologischen Konzept basiert.
Glasklares Wasser und ein konstanter MikronÀhrstoffgehalt pflegen Dein SANGOKAI Riffbecken optimal und versorgen es auf einer breiten und soliden Basis. Weil keine partikulÀren Futtermittel zur Anwendung kommen, die von den Riffbewohnern schlecht oder gar nicht verwertet werden können, wird auch die Mulmbildung auf ein Minimum reduziert. Dein Riffaquarium bleibt vital.
Die gelösten NÀhrstoffe lassen sich mit der Strömung sehr leicht und v.a. schnell im gesamten Becken verteilen. Dadurch können alle im Aquarium lebenden Organismen optimal erreicht und ernÀhrt werden, d.h. neben Korallen und anderen sessilen Wirbellosen auch alle Bakterien, Mikroben und alle Kleinstlebewesen.
Ăbrigens, das BASIS-System gibt es auch fĂŒr kleine Nanoriffaquarien. Das SANGOKAI NANO BASIS-System bietet Dir alle Funktionen und Vorteile des BASIS-Systems, abgestimmt auf Dein kleines Riffbiotop.
