This article will combine the popular fish farming topics on the Internet in the past 10 days and use structured data to analyze the key points of water changes in summer.
1. Data analysis of water change frequency in summer
| Fish tank capacity | water temperature range | Recommended frequency of water changes | Single water change volume |
|---|---|---|---|
| 30-50L | 26-28℃ | every 3 days | 1/3 water |
| 50-100L | 28-30℃ | every 2 days | 1/4 amount of water |
