Replenish FAQ

What is Replenish?
Replenish is a liquid supplement designed to replace minor and trace elements that are depleted in marine aquariums over time.

What does Replenish do?
It replenishes essential trace and minor elements used by fish, corals, and invertebrates, especially those removed through protein skimming and chemical filtration.

Why are trace elements important in a reef aquarium?
Trace elements are involved in biological processes such as growth, coloration, and metabolic functions in corals, algae, and other organisms.

What does Replenish contain?
It provides 29 minor and trace elements in ratios found in natural seawater and excludes unnecessary elements not known to benefit marine organisms.

Is Replenish safe for fish, corals, and invertebrates?
Yes. When used as directed, it is safe for all marine aquarium inhabitants.

When should I use Replenish?

• As part of regular aquarium maintenance
• When using protein skimmers or chemical filtration
• When corals appear dull or lacking coloration
• In systems with high biological demand

How often should I dose Replenish?

• Typical use: every other day in small amounts
• Alternative: weekly dosing, gradually increasing based on system needs

How do I dose Replenish?

• Shake well before use
• Add approximately 0.5 ml per 25 gallons every other day
• Adjust dosing based on livestock response and system demand 

Can I overdose Replenish?
It is best to start with a lower dose and increase gradually. Excessive dosing is unnecessary and should be avoided.

Do I need to test for trace elements before dosing?
Not typically. Most trace elements are difficult to test accurately, so dosing is usually based on observation of livestock health and coloration.

Does Replenish replace water changes?
No. It supplements trace elements but does not replace regular water changes.

Can I use Replenish with other supplements?
Yes. It is commonly used alongside calcium, alkalinity, and magnesium supplements as part of a complete reef care program.

What problems does Replenish help address?

• Loss of trace elements due to filtration
• Dull coral coloration
• Reduced biological performance in reef systems

Is Replenish required for all aquariums?
Not always. It is most beneficial in reef aquariums with corals or systems with heavy filtration and higher demand for trace elements.
