Coralline Algae in a Bottle, Purple Helix ®
This is our original time tested product with a proven track record and amazing results. Why wait 6 months to a year for coralline to show up when you can seed your tank now with multiple hardy and colorful strains of Coralline Algae.
Coralline Algae in a Bottle is the ONLY product developed in a laboratory that contains actual live algae spores. Other similar products are simply a mixture of calcium and magnesium, both of which are already contained in all salt mixes, and are rarely ever lacking in a newly setup aquarium. If your levels are not low then using these “purple algae accelerators” provide absolutely nothing and we don’t want you to fall for the marketing hype.
Coralline Algae in a Bottle is available only online. You won’t find it on the shelves of big chain stores because it is a live product and has a shelf life of only 14 days. Most marine bacteria will not survive more than a few weeks without oxygen and a source of energy. This is the reason for the effectiveness of this product. Every order is bottled fresh and does not sit on a shelf for a year.
Coralline Algae & Nitrifying Bacteria:
- Unique 2 in 1 formula contains both live coralline algae spores and active nitrifying bacteria.
- Every bottle includes 7 separate species of coralline, this maximizes the color variations and varieties that will populate throughout your tank.
- Purple Helix blend 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.
- Aids in rapidly establishing your tanks biological filtration using fresh multi-strain bacteria bottled on the day that it is shipped.
- 100% all natural formula. No sulfur, copper, or phosphates.
- Highest concentration of beneficial nitrifying bacteria which remove harmful nitrogenous waste.
- Establishes a natural organic balance in your aquarium.
- Helps cycle new fish tanks and eliminate new tank syndrome.
- Safe for use in all reef tanks and with all species of fish and coral.

Worked exactly as expected. Had coralline algae growing in my tank in a couple of weeks instead of a few months. Very impressed, will definitely recommend.
Becky Stateman –
Fan-Tas-Tic!! Being looking for something like this for a long time, results were more than I even expected.
David Levy –
6 Months of reporting and I have to say it worked really great. Was part of a beta testing group that received the product for free when I purchased dry rocks from them 6 months ago. I had to report once a week on growth and of coralline algae in my tank and I was only allowed to add fish, no other rock or inverts. I’m super happy with the colors on my once dry rock. It doesn’t happen overnight but their product really works amazing. Great company too and we had quite a few laughs with my reports. Thanks again and glad I could be of help, I hope my experiences and feedback with your product has helped shape it into what it is now.

Worked well for me. Searched everywhere for coralline algae for sale, is good stuff

WOW is all I can say! It’s been several years since I set up a saltwater tank. I knew that it was important to start a tank with a good base of bacteria in order to accelerate the cycling of the tank. Rather than just sitting back and waiting for the process to slowly complete, I did a little research and stumbled upon this product… and I am SOOOOO GLAD that I did! The nitrifying bacteria helped accelerate the cycling process in a big way. I expected to wait a month before the tank would cycle but it completed within just a couple of weeks. Not only that, but there is CORALLINE ALGAE already growing on my rocks! Light pink, dark pink/red, bright green… I’m really impressed with how well my tank is thriving so early on. I visited a friend yesterday whose tank has been running for over a year with Kessell lights and an impressive sump/refugium. My tank is much simpler and is showing more coralline growth than theirs is! From prior experience with salt tanks, I KNOW this is not just a coincidence. I will definitely use ARC Reef’s Coralline Algae in a bottle for all future tank setups. Can’t wait to see what other products they produce, I’m a fan for life!

This stuff is the real deal! In the past I have used Purple up to help push along the coralline on new tanks. It works, but not very well. This product is a totally new approach and it really, really works. My tank has been up and running for about 2 months. I added this stuff and now I have an explosion of purple and pink coralline throughout the tank. I was skeptical at first but I have purchased live rock from ARC in the past and was very pleased with its quality so I decided to give this a try. I am so happy with the results that I purchased 2 more bottles today that I will be seeding to a 50 gallon reef I just setup. If you want coralline on your rock quickly. Use this product.
Eric Smith –
We had ordered the algae in a bottle during the month of January and the bottle we had recieved did not work. Tom in customer service was able to address my issue and said it may have frozen during shipment. He took care of me promptly and sent me 2 replacement bottles packed up as to not freeze again! Because of their excellent service I will use these guys again for all of my reef needs!

I’ll be honest, I thought it was going to be snake oil. I probably even did it wrong BUT:
I set up my 150g Fish only with dead rock (Marcos) which was as white as the driven snow, No fish. Right off I put in 3 bottles of this stuff and followed the instructions, turned only the blue LEDs on continuously for 2 weeks. Then I did a fishless cycle with Dr Tims One and Only which took about 3 weeks. Still nothing purple anywhere. I just knew I probably killed whatever spores were there by not cycling first. Over the next couple of weeks I added a couple of fish and I looked down from above during a feeding And saw a bunch of dark purplish spots starting to form on parts of the rock. I thought oh crap here comes the cyano. But it wouldnt rub off, so I knew I was onto something. Every day now the spots are more prevalent and getting bigger, some now the size of half a dime. The only thing living that I added were the fish, no live rock, nothing that had been in water in the last several hundred years. At the current growth rate it will be substantially covered in a couple of months. So unless Dr Tims one and only has coralline spores (Im sure this isnt the case) then there is only one source, the Coralline in a Bottle. I would never have believed it, But IT WORKS!! I have two Current USA 96W LED fixtures, used perfect RO water, skimmer, UV sterilizer and filter socks. Water tests at 0 nitrates and 0 phosphates about 6-7 weeks after the first fill. I highly recommend this to anyone.

Snake oil. I purchased a bottle of purple helix nearly 2 months ago and I have zero coralline growing in my 175 gal reefer. Tank parameters are perfect, including calcium alk nitrate and phosphate. Wrote arcreef for any suggestions they may have and no response whatsoever. You’d be better off going to your LFS and asking them to scrape some live rock from a (safe) DT tank so you can introduce it to yours.
ARCreef –
Hi James,
We are sorry to hear that you did not achieve the intended results in your particular setup, please be advised that you do need 1 bottle per 50 gallons of tank volume (including sump). You would need an additional 3 bottles for your 175 gallon tank. Our product will still work if under-dosed but it will require a considerable amount more time in your very large tank to achieve the same results. The time frame given on the bottle is stated based on dosing 1 bottle per 50 gallons. We do value all feedback and we assure you that we are working daily on adding additional species of coralline algae that have faster growth rates. We thank you for your feedback and are willing to bet that in the very near future will see your coralline spots show up. Each bottle contains 6 separate strains so you will see different colors also. Good luck and Happy Reefing!
Karen Gifford –
Wow!!! They say the results won’t happen overnight, but for me they did! Less than 24 hours after adding to my tank I saw purple pox forming! My guess is that my tank was well cycled and stable (up and running for 3 months), and I just needed to introduce the spores to seed the tank. It has been 48 hours now… eagerly watching the transformation.
Brent (verified owner) –
All I can say is that this stuff is incredible. I saw the purple spots less than 24 hours after adding it to my tank. About a month later, I am getting incredibly fast growth on my dry rock. Most of the tops of the rocks are covered in a nice purple carpet already, with the sides and bottoms of the rock also seeing some growth. I recommend this product to everyone I talk to about my tank, and will continue to do so forever. Keep on making an amazing product, ARC!

This isn’t a magic potion that instantly turns your tank purple. Like anything in this hobby good things happen to those that wait. I’m probably 5 months into 3 bottles in a 150 gallon and the colors of purple are awesome.
Will be ordering more in a few months
Thanks.
Tom (verified owner) –
…works great! I’d post a picture if i could. Put in a one month old tank 5 months ago…REALLY starting come alive with deep purple. As with ALL things in this hobby…takes a little time.

This is to redact my previous review. I believe the first issue I had was with my RO/DI water. I couldn’t get any growth out of my corals and my invertebrates were struggling with the cheap unit I bought. So I decided to purchase a 7 stage RO/DI from BRS and everything started growing in my tank very quickly, including coralline algae! ARC Reef was very helpful with my second order and I will be purchasing more soon for another system I’m setting up. Don’t make my mistake, order enough for the size of tank (1 bottle per 50 gal) and take every step necessary to assure that your water conditions (specifically your source water) are adequate to get it to grow.

I was very skeptical it wouldn’t work but it’s only been 4 weeks and I have small patches of purple growing on my rocks in a few places also have pink patches as well! Very exciting to see so quickly!

I bought a bottle of the purple and the pink for my aquarium and turned everything but the lights and pumps off for three days. This is a new tank 125 gallon, and I used dry reef rock. It has now been a week and small tan spots showing up on the rock and on the resin bubble unit in the tank. The spots started showing up 2 days ago and have gotten bigger each day. My tank is going through the cycling process. It has no fish. Today I added 3 pieces of live rock to help the other rock seed. There were a few hitch hikers on the three pieces of rock..2 bumblebee snails, 2 coral polyps, and a brittle starfish that was inside a cave in one of the rocks. All are doing well so far. Based upon what I have read, the coralline spots will continue to multiply and the purple/pink colors will begin to show up. The product is great. I look forward to seeing the growth continue!

Received my bottle of Pink coralline algae today. The “bottled on” date is 02/07/2019, but the ship date was 02/06/2019. Can’t help but wonder how long the product sat on the shelf before being shipped.
ARCreef –

It is a working product. I under fed my 180 gallon tank 2 bottles about 4 months ago and played the waiting game. I made the rock myself so it was pure white, Most, if not all of the rocks and now covered with purple, pinks and even bright green, I really can not believe the results from this product….with I could post a pic of the rock so you could all see the proof!!!
Chad Paolucci (verified owner) –
Had my reef tank up.and running for about 6 months with some coraline already in tank from live rocks and such. I wanted some more especially on the base rock and on rock with not so much. Within 4 weeks i started seeing results of this product working after 8 weeks i had visibly new algae growth on glass filters powerheads rocks even on a section of sand .amazing product definitely recomend the use of this for new or established tanks whom want more coraline

Unfortunately, the product does not seem to work. I’ve seeded tanks with rocks with coralline but wanted to try this on a brand new 75 gallon tank. The tank was set up with all dry rock and no sources of coralline to give it a real test. Tank is about 79 degrees with appropriate calcium/alkalinity levels along with other parameters. I followed the instructions to the letter but it has now been about 14 weeks and not a sign of coralline at all. There were no rocks in the bottles, just looked like water. Shook the bottles and filled multiple times per instructions as well.
I reached out to the company via email and instagram but it took 2 weeks to get a response. I finally got a response on Instagram acknowledging that they had a new source tank and now include rock pieces and a brush with each bottle. I was informed mine must have been bottled before the change but they apologized saying they would send me new bottles with the new formula and packaging. I was very happy with the response and was told the would get it done by the next few days. That was on June 24th. It is now August 2nd with no response at all. I’ve sent numerous emails and private messages on Instagram as well but nothing. Unfortunately, the product didn’t work or maybe the new bottling might. I’ll never know because there is no response at all from the company. The customer support has been non existent.

This product absolutely works. One thing to remember is your tank’s conditions must be correct before adding this product.
I started with dry rock and dry sand and no other sources of coralline. Within a month or so of adding the product, I have tiny 1/16″ to 1/8″ size spots of coralline all over the dry rock! I’m very happy with the results.
