What should I do if the water turns cloudy after a water change?

This is usually caused by a minor disruption to the nitrification system, or by stirring up dust from the substrate bed. Just let the filter run, and it should clear up on its own within 1–2 days.

Does the fish feel uncomfortable after a water change (e.g., lying on the bottom, jumping)?

The most common reason is that the temperature difference is too large, or the water quality fluctuates sharply (e.g., pH, GH).

The hose hardens, turns yellow, or smells.

Cause: With prolonged use, algae and bacterial biofilms grow inside the tube, or the plastic ages. Solution: Regular cleaning: rinse the hose with hot water.

The siphon cannot be started (the water cannot be suctioned out).

Cause: The position of the water outlet is not low enough. Solution: Make sure that the position of the bucket or drain is much lower than the water level of the aquarium. The greater the gap, the stronger the siphon.
