There is No Faster Way To Turn Bare Rock Into Beautiful Coralline Encrusted Live Rock!

Pink Fusion Coralline Algae is a truly unique product that contains multiple species of live coralline algae spores and nitrifying bacteria in a single solution. Unlike many other coralline algae accelerators that are mostly just calcium and other elements, ARC Reef's Pink Fusion contains live algae that will populate on your reef tank's surfaces to create a vibrant pink crust over your rocks. Coralline algae has multiple beneficial effects for your saltwater aquarium, from discouraging nuisance algae growth to providing a habitat for beneficial bacteria and other microscopic creatures. Pairing Pink Fusion Coralline Algae with Purple Helix will give your tank a very natural coralline algae look much quicker than any other method.

1 8oz. bottle treats up to 50 gallons. If your tank is more than 50 gallons it is recommended to use 1 bottle for every 50 gallons of tank volume. You cannot overdose your tank with this product.


Most reefers will start to see colored spots appear within a couple weeks however it can take up to 3 months before effects can start to be seen. Coralline algae does not grow super fast and patience is a virtue when it comes to any saltwater aquarium, but making sure that your tank parameters are in the correct ranges and steady can help accelerate the growth (see tips below).

Goniolithon, Lithophyllum, Lithoporella, Metamastophora, Sporolithon, and Mesophyllum


Ingredients - Purified seawater, lab-cultured pink coralline algae spores, nitrifying marine bacteria (heterotrophic, chemolithotrophic and autotrophic), calcium carbonate, potassium carbonate ion buffer. 


What's Included?

1x 8oz Pink Fusion Coralline Algae



Raise your Temperature. Coralline algae grows very slowly, its growth rate is approximately 10x’s more rapid in tropical waters than in the Arctic. If the temperature of your tank is below 78 °F. then increase the temperature to 78-82 °F. this will increase the reproductive growth rate by nearly 15% Make sure to keep the temperature stable with a heater controller.

Aquatic Life Loves Stability and so Does Coralline Algae. You must keep your water parameters stable through regular monitoring and water testing. Smaller more frequent water changes are preferred over larger less often water changes, this helps eliminate any shock to the spores. Salinity and PH are the 2 most important parameters to keep stable.

More Frequent Water Changes. You should be doing regular water changes at least twice monthly. Nearly every problem can be fixed with a water change. High nitrates? Water change! Cloudy water? Water change! Nuisance algae? Water change! Got ick? Water Change! Are corals shriveling up? Water change! Spending all your money on corals? Ok, well that’s one that a water change can’t fix but for nearly everything else, a partial water change will fix, or at least give you more time to find the problem. Your aquarium is a closed system and can easily be put off balance.

Have Patience. If you’re new to the hobby this tip will save your hard-earned cash from being flushed down the drain. Only bad things happen overnight in this hobby. Add livestock slowly and never change anything quickly. It’s best to think of your aquarium like a very old man, it doesn’t adapt well to change (and at times can smell like an old sock!).

Product Questions

the wwc/brs 750xxl got aiptasia from coraline. is there ANY chance at all that this bottle has a single spore of aiptasia??? thanks!
Question by: Glenn Rudolph on Mar 31, 2020, 8:42 PM
Hi there,

The bottle will not have any aptasia in it. The reason that tank got aiptasia is Ryan took coralline from the 160 and basically put the aptasia in the tank.

Take care
