Reef Code A & Reef Code B – FAQ
What are Reef Code A and Reef Code B?
Reef Code A and Reef Code B are a two-part liquid system designed to maintain proper calcium and alkalinity levels in marine aquariums.
What does Reef Code A do?
Reef Code A is the calcium component. It increases calcium levels in the aquarium, which is essential for coral growth and skeletal development.
What does Reef Code B do?
Reef Code B is the alkalinity (carbonate) component. It helps maintain alkalinity, stabilizes pH, and supports overall buffering capacity in the aquarium.
Why are Reef Code A and B used together?
They are designed to be dosed together in equal proportions to maintain calcium and alkalinity in the same balanced ratio found in natural seawater.
What types of aquariums are Reef Code A & B for?
They are intended for reef aquariums with corals, clams, and other calcifying organisms that require stable calcium and alkalinity levels.
What are the benefits of using Reef Code A & B?
- Supports coral growth and skeletal development
- Maintains stable alkalinity and pH
- Provides balanced calcium and carbonate levels
- Helps simplify calcium and alkalinity dosing
When should I start using Reef Code A & B?
- When your aquarium contains corals or calcifying organisms
- When calcium and alkalinity levels begin to decline
- After your tank is fully cycled and stable
How do I dose Reef Code A & B?
- Dose both parts separately (do not mix together before adding)
- Typically dose equal amounts of each
- Adjust dosing based on test results for calcium and alkalinity
Can I dose Reef Code A and B at the same time?
No. Dose each part separately, ideally spaced apart, to prevent precipitation.
How often should I dose Reef Code A & B?
Dosing frequency depends on your tank’s consumption rate. Most reef aquariums require daily or every-other-day dosing.
What parameters should I monitor when using Reef Code A & B?
- Calcium (target ~412–450 ppm)
- Alkalinity (typically 7–12 dKH)
- Magnesium (recommended ~1290–1320 ppm for stability)
What happens if calcium or alkalinity becomes unbalanced?
If one parameter rises or falls faster than the other, dosing amounts may need to be adjusted independently to restore balance.
Can I use Reef Code A & B with other supplements?
Yes, but avoid using other calcium or alkalinity supplements simultaneously unless specifically adjusting levels.
Do Reef Code A & B contain unwanted additives?
No. They do not contain phosphate, silicate, or organic material.
What problems do Reef Code A & B help prevent?
- Poor coral growth
- Weak skeletal structure
- pH instability
- Alkalinity swings
Are Reef Code A & B beginner-friendly?
Yes, but regular testing is required to properly dial in dosing and maintain stability.
