Another method is to grow algae in tanks using sugars as the energy source. Phosphorus is often enough available in the form of Phosphate PO4. The amount of minerals they need to grow well will of course vary with the macroalgae you keep in your marine aquarium, how often you do saltwater changes and what kind of livestock you keep in the aquarium. SCIENTIFIC … NitrateNitrate is by far the most important mineral for macroalgae to grow. Autotrophic growth requires carbon, hydrogen, oxygen, nitrogen, phosphorous, sulfur, iron, and trace elements. The lack of nutrients will the production of algae. We have actually good experiences with an Iron level between 0.05-0,1 ppm. With the right water conditions you will find it quite easy to keep macroalgae successfully in your own Marine Aquarium Display Tank or Refugium / Sump and enjoy them watching growing and transforming you Marine Aquarium in a beautiful Planted Fish or Seahorse Tank or Planted Reef Aquarium together with Soft & Hard Corals.Although macroalgae are not plants they will need almost the same essential elements like plants and beside the of course the very important factor of the correct lighting (which we cover in another post ) they will need the right water parameters for macroalgae and some major and minor minerals to grow well and stay healthy.Opposite to plants macroalgae don't grow with roots and therefore the nutrients need to be supplied through the water and not through the substrate ( like Freshwater aquarium plants which can be fed by fertiliser through the substrate).

Red macroalgae species for the Reef Display Tank, Best water conditions for macroalgae growth in the display tank / refugium. ), water and CO2. Unlike its land-based cousins, seaweed doesn't need roots or a system for transporting water and nutrients. Algae absorb the nutrients through their entire body. Algae Sources. We can not take any responsibility for this! Phosphorus is another important nutrient that marine plants need to grow. They interact with the physical, chemical, and biological makeup of the water. It will require scientific-technical knowledge and practical approaches like any other economic activity. Aecio D’Silva, Dr. John Kyndt and MSc. They also use minerals and vitamins in smaller amounts. • Algae can grow (or be adapted) in adverse conditions like deserts and saline and/or brackish water. Two important nutrients for algal growth are nitrogen (N) and phosphorous (P). Leaves and other dead plant material are excellent, however you will need some source of nutrients. To keep the nutrients in your tank to a minimum, feed your fish just once a day, or feed them smaller portions two or three times a day. Be careful with normal Iron Solutions, as they might include Nutrients/Elements, which can be harmful to the marine aquarium inhabitants. For macroalgae, it is recommended to keep the Alkalinity between 7-10 DKH, and the PH Level between 8-8,4. Macro Nutrients Nitrogen. • Algae also produce a vast array of natural products: pigments, proteins, enzymes, amino acids, and vitamins • Some algae have lipid content of up to 70% and up to 86% of starch • Algae can grow (or be adapted) in adverse conditions like deserts and saline and/or brackish water.

Either to enjoy them in your planted marine aquarium tank for the beauty of them like of some beautiful Gracilaria macroalgae species (and of course for more clean marine water by lowering your Nitrate & Phosphate level whilst growing ) or to let them do the big nutrients Export job in your refugium / Sump, using great working macroalgae species like Chaetomorpha or Caulerpa. Nutrients; Nutrients promote and support the growth of algae and Cyanobacteria. Other minor Nutrients are as well beneficial for the growth of macroalgae, but they are normally sufficiently replaced by water changes. Main Nutrients for macroalgae in Planted Reef Tanks / Planted Refugium.

The algae starts to multiply within the next 3 to 5 days. It will be commonly sufficiently available in the marine water as it will be replaced by saltwater changes ( Please check the salt used, that it includes Potassium ). These cookies do not store any personal information. This website uses cookies to improve your experience. Plants like lilies, cattails, and watercress suck up these nutrients and prevent algae from using them to grow. Especially calcareous macroalgae species like from the Halimeda family will need a higher calcium level for its growth. Phosphorus. For the nutrient removal system you are developing, do you think the species that you are growing in the tank are suitable? Carbon will be sufficient enough available in most marine aquariums and the produced oxygen will be helpful when the marine aquarium inhabits a lot of fishes.In planted marine Aquarium / Refugium it may be necessary to add Carbon for example with a CO2 reactor. This website uses cookies to improve your experience while you navigate through the website. Calcium can't be easily added to the marine aquarium like other nutrients/elements, as the available calcium in the marine water depends and influences directly with the Alkalinity and PH Level of the marine water. There will be some species which may need different water parameters and of course it is important to have in mind the water requirements for the corals kept in the same aquarium.If you are unsure if your water parameter are right for growing macroalgae please don't hesitate to contact us. Algae can be grown both outdoors in large open ponds using the sun’s energy, non-potable water, natural and/or man-made CO2 and nutrients. But opting out of some of these cookies may have an effect on your browsing experience. Algae Natural Food will transform the Cargill Malt processing water and CO2 into a source of energy and nutrients for the cultivation of its organic microalgae. Macronutrients include nitrate, phosphate and silicate. Nutrient solutions, as opposed to fertilizers, are designed specifically for use in aquatic environments and their composition is much more preci. Algae also need nutrients to grow and they find the nutrients in water. When your Nitrate Level is too low because you have a Planted Reef Tank, Planted Refugium / Sump you might need to add Nitrate to your water.
