| parameters | ideal range | Monitoring frequency |
|---|---|---|
| Salinity | 30-35‰ | daily |
| pH value | 8.1-8.4 | weekly |
| temperature | 24-28℃ | daily |
| Ammonia nitrogen content | 0ppm | weekly |
| nitrite | 0ppm | weekly |
3. Practical skills for seawater maintenance
1.Change water regularly:Change 10%-20% of the water volume every week to keep the water quality stable.
2.Filtration system:Choose suitable filtration equipment, such as protein skimmers, biological filtration, etc.
3.Lighting control:Marine fish and corals have different light needs, and the light time and intensity need to be adjusted according to the species.
4.Feeding management:Marine fish have diverse feeding habits and need to be provided with live bait, frozen bait or special feed.
4. Frequently Asked Questions and Solutions
| question | Reason | solution |
|---|---|---|
| fish death | Sudden changes in water quality or unsuitable salinity | Adjust water quality slowly and avoid drastic changes |
| algae bloom | Excess nutrition or too much light | Reduce feeding and adjust lighting |
| coral fade | Insufficient light or poor water quality | Improve lighting conditions and change water regularly |
