How to improve Macroalgae growth in the Marine Tank/Refugium

Macroalgae will need to grow well in the marine aquarium mainly Nitrate and Phosphate beside some other minor and major elements like mainly Magnesium, Calcium, Potassium, Sulfate and Iron.  Beside having the fitting light conditions to grow macroalgae it is very important to have all the nutrients constantly available in the reef tank as otherwise the macroalgae might starve or die off. Dosing nutrients in a planted Reef Tank or planted Refugium can be the key for a better macroalgae growth, especially when fast growing macroalgae species like Chaetomorpha / Chaeto or Caulerpa species are used in the refugium, as they will need to have always enough nutrients available.

Best water conditions for great macroalgae growth in the Display Tank or Refugium!

For a macroalgae tank we recommend the following water parameter: Temperature: Between 23-28 °C  ( A higher temperature will stress most macroalgae species and can damage them ) PH: 8-8.4 Alkalinity: 8-11 Salinity: 1.024 - 1.026 Nitrate: Between 3-10 ppm, minimum 2ppm Phosphate: Below 0.5 ppm, good is 0,03 ppm, minimum 0.02ppm Magnesium: Around 1200 ppm - 1350 ppm Calcium: Around 400 ppm - 450 ppm ( high levels are important for calcified species like Halimeda) Iron: Around 0.01 ppm Iodine: around 0.04 ppm Should the chaeto / macroalgae not grow well or if the algae suffers dosing of a specialised fertiliser for the marine aquarium is recommended.

Macroalgae for Herbivore Fishes like Tang, Foxface etc.

Which Macroalgae Can You Add To A Display Tank With Herbivore Marine Fishes  We often get the question what macroalgae we would recommend for herbivore fish species, like the various Tang Species, the Foxface, Algae Blennies etc. The answer to that question is unfortunately not as easy as it seems, as not every species has the same taste like not every Yellow Tang likes the same algae species.

Macroalgae for Seahorses

Macroalgae in an Seahorse Aquarium to create a natural environment for those beautiful animals to make them feel comfortable as much as possible. Not that the right macro algae species will provide them a natural holdfast which will look much better than a plastic chain or similar, some macroalgae species offer a hunting place for the Seahorses to catch rotifers and copepods.  Especially the blue Ochtodes or the Green Bush marine macroalgae are perfect for this. Beside this macroalgae will increase the oxygen level in the Seahorse Tank and improve the water quality when growing, by taking out unwanted nutrients like Nitrate and Phosphate.Find HERE more macroalgae species which we recommend for a seahorse aquarium.

INTRODUCTION TO MARINE MACROALGAE

INTRODUCTION TO MARINE MACROALGAEMacroalgae, or sometimes so called seaweed, seems to have become within the last years more and more popular amongst marine aquarium hobbyists. Previously macroalgae were often used specifically to provide a natural way to export the nutrients in the aquarium water, which means that the algae will grow by using compounds like nitrate, phosphate, ammonium and some heavy metals in the tank water. During this photosynthesis process, it uses carbon dioxide too and turns this into additional oxygen for the aquarium inhabitants. As well it will help to raise the pH level in the tank and increase the tank carbonate buffer capacity, which means are more stable alkalinity level. In addition, it is often used to provide additional hiding spaces for copepods and rotifers. Nowadays thanks to the variety of available macroalgae species, macroalgae can still fulfil these very important functions but they add a very important benefit too . . . . . . a beautiful and more natural looking tank.
