Shrimp often struggle after big, sudden maintenance even when test results look acceptable on paper. Matching temperature, minerals, and routine is usually more important than trying to make the tank look spotless every weekend.
Common safer habits
- Use modest water changes rather than huge swings.
- Match source water as closely as possible every time.
- Clean gently so you do not strip too much biofilm at once.
- Watch the pattern after each maintenance session and adjust slowly.
Where shrimp repeatedly die after water changes, the issue is often instability, mismatched remineralisation, or maintenance that is too aggressive for the tank.
