CaribSea PurpleUp™ is an award-winning, US-patented coralline algae accelerator designed to transform dull live rock into a vibrant, colorful ecosystem. Rather than acting as a standard fertilizer—which would fuel undesirable hair and bubble algae—PurpleUp uses a specialized, dual-method approach. First, it introduces ionic calcium to instantly raise dissolved calcium levels in your water column. Second, it delivers Super Sea Calcium™—a 10-micron aragonite powder that coats live rock surfaces and dissolves locally to supply calcium, strontium, magnesium, and carbonate exactly where growing coralline algae need it most. Completed with a steady replenishment of critical iodine, this bulk 1-gallon jug is the perfect, highly cost-efficient solution for large reef systems and maintenance professionals.
Key benefits
Patented Growth Accelerator: Awarded US Patent No. 7,565,883 for its highly effective, targeted coralline algae growth formula.
Vibrant Rock Coloration: Rapidly promotes beautiful pink and purple coralline algae growth to crowd out pest algaes.
No Nuisance Algae Spikes: Formulated without phosphates or chemical fertilizers, ensuring it will not trigger hair, slime, or bubble algae.
Replenishes Critical Iodine: Delivers an ongoing source of clean iodine, an essential element for healthy coralline algae tissue.
Great for Stony Corals: Supplies the key minerals needed for the skeletal calcification of SPS and LPS corals.
Specifications
Net volume: 1 Gallon (3.78 L)
Form: Aragonite suspended liquid
Primary purpose: Rapid coralline algae growth and calcium replenishment
Water type: Saltwater (Marine reef systems)
Intended users: Marine aquarists, reef keepers, and commercial maintenance services
Suggested use
Dosing Rate: Add 1 capful (5 ml) of PurpleUp per 50 US gallons of aquarium water no more than once daily.
Application: Shake vigorously before use! Pour directly into high-flow areas like sumps or near powerheads for rapid dispersal. Note: PurpleUp will cause temporary water cloudiness while dissolving.
Testing: Wait at least 1 hour after dosing before testing calcium levels to prevent false, elevated test readings. Maintain calcium between 380 ppm and 420 ppm.
Ingredients Ionic Calcium, Aragonite Super Sea Calcium™ (calcium, strontium, magnesium, carbonate), Iodine.
Guaranteed Analysis
Rich in ionic calcium and essential coralline-stimulating micronutrients.
Storage and safety
Store in a cool, dry place. Keep cap tightly sealed.
Keep out of reach of children and pets.
Warnings
For marine aquarium use only. Not for human consumption.
Do not exceed a calcium concentration of 420 ppm, as this can cause mineral precipitation in your tank.
Note: PurpleUp does not contain live coralline algae; some existing live coralline must be present in the tank to act as seed cultures.
What’s included
1 x Jug of CaribSea PurpleUp Coralline Algae Accelerator (1 Gallon / #01530)
Why choose CaribSea PurpleUp 1-Gallon is the absolute best value choice for large display aquariums and professional reef maintenance. It cuts out the complicated, expensive recipes of mixing multiple dosing components to achieve coralline growth. In one patented, highly stable bottle, you get a clean and safe way to establish stunning, algae-resistant pink and purple rockwork.
