## Description

Contains 7 species of Coralline Algae (pink, creamy light pink, fuschia, hot pink, lavender, and magenta). Species of coralline do slightly shift colors depending on their environment especially with differences in lighting and magnesium levels but these species of coralline will generally stay within these shades of pink. Developed in a laboratory and contains actual live algae spores. Other products are simply a mixture of calcium and magnesium. Will also aid in establishing your tanks biological filtration, by providing fresh living bacteria. Our Pink Fusion algae strains are highly epiphytic stains that will help to outcompete other nuisance algae and diatoms. Effective in improving water quality by controlling ammonia and nitrite levels. Reef safe for all marine fish and corals and our holding tanks are 100% fishless so there is no chance of parasites. This is a live product and must be used by the date printed in the bottle. Every bottle is bottled fresh on the date that it ships and has a 21 day shelf life. For Saltwater Use Only. 1 Bottle Treats up to 50 Gallons. Developed and manufactured by ARC, a licensed aquaculture laboratory permitted and licensed under the National Oceanic and Atmospheric Administration, the Department of Agriculture, and the Florida Fish and Wildlife Conservation Commission. 1 Bottle per each 50 gallons of tank volume (including sump) is needed for best results. You can combine both products to give you a total of 14 species. Please ensure to read the included directions and tips before use.

Review: Visible signs in 4 weeks! - I’m pretty sure my results aren’t the norm, but I have many growing spots after only 4 weeks. Many spots! I added this bottle as soon as I was past the initial cycle of the tank. My diatom bloom isn’t even over and I noticed that some spots weren’t rubbing off the glass… As I gave the spots a closer look, there were a lot of them all over the glass. Sure enough, they’re the good stuff… and they’re growing. I’ll be breaking out the razor blade to remove them from the front glass very soon. I will note this: I have kept my parameters very constant and stable since day one, via water changes. Alk @ 8 dkh, Ca @ 350, Mag @ 1050, pH @ 8.2, salinity @ 1.024. I don’t keep my parameters on point for the coralline, but rather it’s just an easy and good practice. Super easy with just weekly 10% water changes for a new tank. But like the instructions say…. You gotta have stability for coralline to thrive, just like with corals. I’d almost be willing to bet that all of the negative reviews are due to the owner not keeping healthy and stable parameters. It’s not a miracle bottle after all, just the spores you need from multiple strains. Treat it right, it’ll grow. PS. No other form of coralline has been introduced to my tank. I used completely dry rock, all new equipment, and I haven’t even introduced a cleaning crew yet, so no snails or hermits bringing it in. I’m pretty sure it didn’t hitchhike in on the pair of clownfish! 😂 This is the whole reason I purchased it to start with… because it was going to be the only way to introduce it for a while, plus I wanted pink!
Review: Don’t hesitate, this stuff is great! - This is the second bottle I have purchased, one through desertcart and the other directly through the business. I’m new to saltwater tanks so my review is from the perspective of relatively little experience but I knew I wanted my rock to have some color! First, the order of purple came fast as I was worried about the product in the mail. It also came with easy to understand instructions so no issue there. A good shake and I put it in my tank and waited. For me, it took about 3 weeks before I first noticed some color appear. From there, it spread as good as I could have hoped. Several weeks later, it looks amazing so I figured I would try the pink next. I haven’t seen a lot of pink on rocks so I really wanted to give it a try. Overall, finding corralline was difficult for me since I’m so new to the hobby. This product is exactly what I was hoping for and the shipping was fast. I would highly recommend it to anyone looking to add a little color and enhance your tank.

## Questions & Answers

**Q: Do I need both the bottle of purple and pink?**
A: Thank you for your question.  As long as you use at least 1 bottle per 50 gallons you can select whichever color you wish, you can use all the same color or mix and match. If you use both you will have a total of 12 separate species of coralline algae.  If you are looking for an end result of only pink or only purple then choose all the same, if you are looking to achieve the greatest bio-diversity or if your tank is resistant to growing coralline algae then you would want to combine both products.  You can not overdose your tank using this product as we do not add calcium or magnesium additives, we use only algae spores and beneficial nitrifying bacteria. Thank you again and happy reefing!

**Q: I have a lot of green algae in my tank.  If I put this in, will it be able to outcompete existing green algae and take over?**
A: It's takes awhile for coralline algae to start to grow. If you have green algae you have to much nutrients. 
I'd work on getting rid of the green algae before putting this in.

**Q: Is there supposed to be anything pink in the bottle?  The liquid was clear, to include the small piece of rock.**
A: No color should be visible. It’s the coralline spores you are after. If conditions are right, it will start to show. I have tried both the purple and pink and have had good luck. Don’t get discouraged mine took about 8 months for me to get my tank under control. Good luck!

**Q: Would pink fusion strain or purple helix strain be best for high lighting sps reef tank?**
A: I used a 50/50 mix in my 75 gallon and both are doing well. It is a reef tank so it sees alot of light from 2 Fluval Marine 32 watt leds

It works for sure. I added it around a month ago, and I'm starting to see some growth on my glass. Be patient and ensure your tank is stable; it will grow.
