Coralline Algae is a crustose type algae due to its hard calcareous deposits contained within its cell walls. It acts as the cement which binds the reef materials into a sturdy structure which will protect the reef and corals from breaking up or dislodging during intense wave action.
Is coralline algae good or bad?
Well-Known Member. Coralline algae is never really a bad thing other than another source for calcium uptake. Sure it’ll be a hassle once it starts growing on the glass and equipment but depending on your tank-taste it may or may not be an issue.
What does coralline algae need to grow?
Like hard corals, coralline algae growth is calcareous by nature, requiring many of the same things coral does to flourish: water Specific Gravity around 1.024. Calcium: 350 to 480 ppm. Carbonate alkalinity: between 2.5 and 4.0 meq/L (7-12 dKH)
What does the start of coralline algae look like?
Coralline Algae often first appears as small white or green patches on aquarium glass and live rock before solidifying into a pink or purple hued coating.
Can coralline algae come back to life?
Coralline might die back with extended (weeks) of darkness, but it’ll come back. If that’s not an option, put it in some coolers or plastic lined boxes and cover it with newspaper soaked in saltwater. It’ll be ok like that for at least a day or so.

How do you use purple up?
Add 1 capful (5ml) per 50 gallons no more than once daily. Place in the sump, near a powerhead outlet, or any high flow area of the system for rapid dispersal. Purple uptm will cause some temporary cloudiness. Check calcium levels regularly.
Do I need coralline algae?
Coralline algae are considered a vital part in every reef and marine aquarium. These algae produce chemicals which promote herbivorous invertebrates. These in turn keep various sea weeds from growing which would otherwise smother the algae or keep them in the shade.
Do snails eat coralline?
It actually seems to hinder coralline growth. My astrea snails can eat coralline algae on glass, especially if i go over the coralline with a algae scraper.

What does coralline look like?
Coralline algae are red algae in the order Corallinales. They are characterized by a thallus that is hard because of calcareous deposits contained within the cell walls. The colors of these algae are most typically pink, or some other shade of red, but some species can be purple, yellow, blue, white, or gray-green.
How long does it take for live rock to turn purple?
If a purple coraline strain is introduced there is no guarantee it will grow. If it does grow it might be on your glass and not the rock. In most tanks I have had with dry rock, it takes from 6 months to a year before I start to see it on the rock.
Do LED lights cause algae growth?
Contrary to what you may have been told, LED lights do not cause algae growth any more than other aquarium lighting options. … This also discourages algae growth more than anything else—because it’s not the kind of light that causes algae growth, but the intensity of it.
What color light stops algae growth?
Our results show that algae grows the best under white light and more in blue light than red light. Therefore, our hypothesis is partially supported because the growth rate was higher under the blue light in comparison to the red group; however, the algae under the control condition experienced the most growth.
Does blue light grow diatoms?
For instance, with moderate light (especially blue light) and high silicate in the water, diatoms will predominate, but with low silicate and high phosphates red algae might predominate.
Is Green coralline algae good?
Coralline algae acts as a food source, structural support system and environmental protector for saltwater, and even freshwater, reef systems. It’s no surprise growing coralline algae is the primary goal for so many marine aquarists.
Does coralline algae consume alkalinity?
The coralline algae is a substantial sink for calcium and alkalinity (and magnesium) in reef tanks, but generally in a balanced fashion (maybe slightly less calcium use than usual as it incorporates a lot of magnesium.
Is there red coralline algae?
Red coralline algae can be found in most marine habitats. Articulated corallines grow mostly in low intertidal and subtidal coastal areas. Crustose corallines have been found in depths up to 500 feet (152 m).

Why does coralline algae turn white?
Sudden Changes in Lighting Conditions Can Cause Coralline Algae to Turn White. … Coralline algae are encrusting red algae, and the two primary elements that all calcareous species of algae need to grow are calcium, to form their encrustations, and light, which gives them color.
Is coralline algae a coral?
Crustose coralline algae play a variety of important roles in many marine ecosystems, particularly coral reefs. We call them coral reefs because their three-dimensional structures are built by stony coral animals, which produce limestone as they grow ever upwards towards the sun.
Do sea urchins eat coralline algae?
Sea urchins feed on virtually all types of algae including calcareous algae (e.g. coralline algae). … Though they are most active at night, urchins seem to eat constantly and are quite indiscriminate in terms of what they eat.

Does coralline algae start Brown?
Most coraline begins green, not brown, and eventually turns pink and purple. The color is also dependent on various trace elements and light intensity.
Does Coraline start green?

Are sponges bad for reef tank?
Regular growth of sponges have usually been encouraged in reef tanks, but that yellow colored sponge is probably leaching toxins into your aquarium water. Sponges are known to release compounds in reef water that stunts, kills and even induces bleaching in stony corals.

The CCA growing on frag plugs and mounts will work just fine.
Can algae grow in saltwater?
Even though marine algae can be very beneficial in the saltwater aquarium, you do not want it to get out of control. … Algae tends to grow quickly in tanks with high levels of nitrate and phosphate, so controlling these chemicals is key to controlling unwanted algae growth.
