## Overview

The Coralline Algae in a Bottle + Nitrifying Bacteria is a revolutionary 2-in-1 solution designed for saltwater aquariums. This unique formula combines live coralline algae spores with active nitrifying probiotic bacteria, promoting a balanced and colorful environment. Ideal for establishing new tanks or enhancing existing setups, it helps combat nuisance algae while rapidly establishing biological filtration.

## Description

Unique 2 in 1 formula contains both live coralline algae spores and active nitrifying bacteria. Purple Helix, Coralline Algae in a bottle is the ONLY product developed in a laboratory containing 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. 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 is best used within 14 days. Every bottle includes a minimum of 7 separate species of coralline, this maximizes the color variations and varieties that will populate throughout your tank. Will also aid in establishing your tanks biological filtration, again with providing fresh living bacteria. Most marine bacteria will not survive without oxygen and an energy source sitting on a shelf for a year, most species can last only a matter of a few weeks. Our 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. Use when setting up a new aquarium, when adding new rock or substrate to your tank, and to boost the color and diversity of existing live rock in an already established aquarium. Reef safe for all marine fish and corals. 100% all natural formula. Every bottle is bottled fresh on the date that it ships. 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.

## Questions & Answers

**Q: Is this the same as Instant Ocean’s Bio-Spira?**
A: This contains both marine bacteria AND coralline algae spores.  Bio-Spira contains only the bacteria. Both will help cycle a tank but only this product will add coralline in addition to the bacteria needed. Thank you for your question we hope this helps.

**Q: Will this replace the need to buy a "seed" rock when starting a dry rock tank cycle?**
A: Yes, this does take the place of a seed rock.  This method is slightly faster and requires less effort on uour part. It would be the equivalent of getting 6 seed rocks and then scraping the algae off in order to release the spores from those rocks into the water column in order to settle on your dry rock. Both methods will work though. Thamk ypu for your question.

**Q: Can I put this I set up my tank 2 months ago?**
A: Yes, it works especially great for tanks that have already cycled like yours.

**Q: Do you add the whole bottle at once?**
A: Yes, add the entire bottle upon receiving it. Each bottle treats up to 50 Gallons. If your tank is larger, then it is suggested to use multiple bottles to ensure the concentration of spores is adequate.
