Water Parameters And Maintenance
Keeping a reef tank healthy means understanding water needs. Different species need stable water conditions to live well.
Regular maintenance helps keep water clean and suitable for all reef tank species. Attention to details makes the tank thrive.
Ideal Conditions For Species
Most reef species prefer water that is warm and salty with steady chemistry. The right pH, temperature, and salinity levels support their health.
| Parameter | Ideal Range |
| Temperature | 75°F – 82°F (24°C – 28°C) |
| pH | 8.1 – 8.4 |
| Salinity | 1.023 – 1.026 specific gravity |
| Alkalinity | 8 – 12 dKH |
| Calcium | 400 – 450 ppm |
| Magnesium | 1250 – 1350 ppm |
Filtration And Lighting
Good filtration removes waste and keeps water clear. Lighting helps corals and other species grow naturally.
