Replenish - Brightwell Aquatics

Restore balance. Support growth. Enhance color.

Brightwell Replenish is a comprehensive trace and minor element supplement designed to replace what your reef naturally consumes and what is removed through protein skimming, activated carbon, and other filtration methods. As corals grow, algae photosynthesize, and biological processes continue, essential elements are steadily depleted—Replenish restores them in the exact ratios found in natural seawater.

Formulated with 29 carefully selected minor and trace elements, this solution delivers only what is known to be biologically relevant in marine systems. No unnecessary additives, no excess metals—just a clean, targeted approach to maintaining long-term reef stability. These elements play critical roles in enzymatic functions, skeletal development, pigmentation, and overall coral vitality, making consistent replenishment key for both growth and coloration.

Built using ultra-pure ingredients and purified water, Replenish is safe for use in all marine aquariums, including mixed reefs, SPS-dominant systems, and fish-only setups. It integrates easily into any dosing routine and pairs well with systems running heavy filtration where trace depletion occurs more rapidly.

Because most trace elements cannot be accurately measured with hobby-grade test kits, dosing is best guided by consistency and observation. Daily dosing helps maintain stable concentrations and avoids the spikes and drops associated with weekly additions, creating a more natural environment for your reef.

Dosing Guidelines

Shake well before use.

Basic Use: Dose 0.5 mL per 25 gallons every other day.

Advanced Use: Start with 1 mL per 10 gallons weekly (or ~0.14 mL daily) for the first 4 weeks. Gradually increase to 2 mL per 10 gallons weekly based on coral response and system demand.

Start low and increase slowly. Overdosing trace elements can be harmful—stability and observation are key.

Best Practices

Maintain consistent protein skimming and filtration to manage organic waste and ensure proper element cycling.

Dose regularly for stable concentrations rather than large, infrequent additions.

Monitor coral coloration, growth, and overall health to fine-tune dosing.
