FMC Acropora tenuis Green

"WYSIWYG" ("What You See Is What You Get") - Coral Original Images.
To make sure you get exactly the coral you want, every single coral is photographed by us. And usually once under daylight illumination and once under blue light.

If you have any further questions, please check our Fauna Marin Support Forum and our  Fauna Marin Reefing Group at Facebook.

If you provide the right current, good lighting and the  right water values, successful keeping of SPS-corals with good growth and great colors is feasible in a marine aquarium.

In contrast to LPS corals ( LPS =  Large Polyp Stoney Coral  ), which usually cope well even with higher nutrient values, sps corals quickly show a loss of color or stagnating growth. Formerly colorful corals often turn an unsightly brown. This is because of the higher nutrients in the water, which promotes zooxanthellae growth in the coral.

SPS corals love clean and clear water. In order to keep SPS corals almost in their natural colors on a long-term basis, you should strive for the lowest possible phosphate and nitrate value in the aquarium.

To successfully maintain corals in the long term, stable water and nutrient levels should be aimed for.
This can be well controlled with various  phosphate adsorbers. With filtration via activated carbon, such as  Fauna Marin Carb L long-life carbon, the water remains crystal clear. Phenols, protein compounds, dyes and nettle toxins are filtered out of the water and rendered harmless.  

Light intensity also affects the coloration and growth of the corals. At Fauna Marin Corals we successfully keep our corals under a mix of T5 tubes (50/50 white/blue), in combination with the  LED lamps.

Important for the care of small polyp stone corals is the constant maintenance of the salinity, as well as the use of a good sea salt, such as the  Fauna Marin Professional Sea Salt. The salinity should always be between 34/35 per mille, respectively 1.022 and 1.024 density. 

A regular check of the density is an absolute must in marine aquaristics. Our  salt calculator helps to calculate the correct amount of salt.

Pay attention - especially in summer - to the temperature in the aquarium. Corals do not tolerate temperatures exceeding 30 degrees for longer periods of time. If this is the case the corals fade, which leads to the so-called Coral Bleaching.

We recommend a regular control of the water values with our  ICP water analysis. 
Based on the results of the analysis, the water values can be adjusted correctly with the help of our dosage recommendations on our  laboratory website.
