Why are my corals turning brown?
The Cause: Corals typically turn brown as a result of the overproduction of zooxanthellae (a type of algae) inside of a corals tissue. As zooxanthellae levels increase, they block the coral’s natural pigments causing them to turn brown.
Do Zoanthids like high flow?
Ideally, your Zoanthids should live in a low to medium-high flow area. If placed in too high of a flow area, polyps will have a difficult time opening, which stunts its growth/development.
Why are my Zoanthids losing color?
Under too much or inadequate lighting parameters, often times, Zoas and Paly’s will dispel and collect a different strain better apt to handle the change in the corals surrounding. Because of this, many times coloration and/or design/ pattern will be different after this transformation.

Why are my corals not colorful?
Coral reefs grow best in waters with a temperature between 25 and 30 degrees Celsius. When the ocean temperature rises just one or two degrees, zooxanthellae will leave the corals or die. Without the algae, corals lose their color and turn white. This is called “coral bleaching “.
Can corals bleach from too little light?
The primary sign of higher light is bleaching or losing tissue and due to low light corals may turn brown in colour.
How many watts of light do I need for a reef tank?
A good basic rule to follow is to provide 1 to 2 watts of lighting per gallon for fish-only aquariums, 2 to 5 watts per gallon for freshwater planted aquariums, and 4 to 8 watts per gallon for reef aquariums.
Do corals benefit from white light?
Corals don’t need a white light to grow in your reef tank. Instead, they need blue light to grow healthily. White light is more useful to humans, as it helps them ‘see’ the corals in the reef tank better.
