Why does SPS turn white?
White tips form either from regular coral growth or they are burnt tips resulting from alkalinity spike or tissue necrosis. When your SPS coral fragments arrive, they would have originated from a very different environment to your reef tank.
What causes SPS to brown out?
The cause of SPS corals turning brown is from the overproduction of the microscopic algae that live inside the coral’s tissues, called zooxanthellae. Zooxanthellae play a vital role in the growth and productivity of corals, as they have a mutually-beneficial relationship.
How do you get good color in SPS coral?
Complete available nutrients package and adequate light are the main contributor to vivid SPS coloration. Some will say red/green are not needed at all, but IME daily bombardment of red/green will help out in color pigmentation.
What causes Acropora to bleach?
Often the cause is too much light, too high or low alkalinity, or something nearby has stung/infected/irritated the coral.
How do I know if my SPS is healthy?
The sequence from healthy to unhealthy is that, tips polyp normally extended in night time #1> tips abnormal in night > tip poly with brown color or extension in light time > tips color changed. This is also the secret of some fantastic “frag” are so colorful, but you cannot keep same color when your SPS are healthy.
Why are my SPS corals dying?
High phosphate can slowly kill corals or cause the demise of newly introduced, sensitive species like SPS corals. Check the phosphate level using a phosphate test kit and lower it using phosphate remover and water changes. Don’t overdose phosphate remover as it can cause the KH to drop suddenly.
Why is my Acropora Brown?
They turn brown when you don’t have enough light usually or your tanks high nutrients and not yet mature.
Why are my corals going 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 SPS corals need 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.
Why are my corals bleaching out?
The leading cause of coral bleaching is climate change. A warming planet means a warming ocean, and a change in water temperature—as little as 2 degrees Fahrenheit—can cause coral to drive out algae. Coral may bleach for other reasons, like extremely low tides, pollution, or too much sunlight.
