Substrate Choices And Benefits
Substrate affects tank health and appearance. It supports plants and animals living in the sand.
| Substrate Type | Benefits | Best For |
| Aragonite Sand | Maintains stable pH and adds calcium | Reef tanks with corals |
| Crushed Coral | Good water flow, prevents compaction | Fish tanks with burrowing species |
| Live Sand | Contains beneficial bacteria | Quick tank cycling |
| Oolitic Sand | Fine texture, natural look | Show tanks with delicate animals |
Coral Placement Strategies
Placing corals correctly in a saltwater tank helps them grow well. It keeps your tank healthy and beautiful.
Good coral placement balances space, light, and water flow. This creates a safe home for each coral type.
Compatibility Considerations
Some corals can harm others if placed too close. They release chemicals or sting nearby corals.
Check which corals get along before placing them. Keep aggressive corals apart to avoid damage.
- Place soft corals away from stony corals
- Separate corals with long stinging tentacles
- Avoid crowding to reduce stress and competition
Light And Flow Requirements
Different corals need different light levels. Some like bright light, others prefer shade.
Water flow is also important. It helps corals get food and removes waste.
- Place high-light corals near the tank top
- Put low-light corals on lower rocks or shaded areas
- Strong water flow suits branching corals
- Gentle flow is best for soft or delicate corals
