Most fish keepers know when something isn't quite right with their tank, but it can be hard to know when to tackle it yourself and when to call in a professional. Here are five signs your aquarium needs expert attention.
1. Persistent algae despite regular cleaning. If algae keeps coming back no matter how often you scrub, the root cause is usually a water chemistry or lighting imbalance. A professional can diagnose the source and fix it rather than just treating the symptoms.
2. Cloudy or discoloured water. Milky white cloudiness often indicates a bacterial bloom, while yellow-brown tints suggest dissolved organic waste. Both signal that the filter or cleaning routine isn't keeping up with the tank's bioload.
3. Fish are lethargic or not eating. Behaviour changes are one of the earliest indicators of poor water quality. If your fish are hovering near the surface, hiding more than usual, or refusing food, test your water immediately and consider a professional assessment.
4. Unexplained fish deaths. Losing fish without an obvious cause like overfeeding or aggression usually points to water quality issues or disease. A professional clean combined with a water test can identify the problem and prevent further losses.
5. It's been more than six weeks since the last clean. Even tanks that look fine can accumulate nitrates and detritus over time. If it's been over six weeks without a thorough clean, your tank will benefit from a full service regardless of how it looks on the surface.
