|---|---|---|
| Salinity | 1.023-1.025 | Optical salinity meter |
| pH value | 8.1-8.4 | Electronic pH tester |
| Ammonia/nitrite | 0 ppm | API testing agent |
3. Introduction of organisms
It is recommended to introduce organisms in stages. The following is the recommended order:
| stage | creature type | function |
|---|---|---|
| Week 1 | Live rock/nitrifying bacteria | Build an ecosystem |
| Week 3 | Clean shrimp/snails | Clean up algae |

| coral fade | Insufficient light/fluctuating water quality | Adjust spectra and stabilize parameters |
| Fish refuse to eat | stress/parasite | Isolation and observation, targeted medication |
4. Summary
Building a saltwater fish tank requires patience and a scientific approach. From the purchase of equipment to the introduction of organisms, water quality and ecological balance need to be strictly controlled in every step. It is recommended that novices refer to recent popular discussions (such as coral feeding tips, low-cost solutions, etc.) and gradually practice based on their own conditions. Remember:A stable system is more important than rapid scene creation!
