How to start (simple plan)
To start cleaning your aquarium, gather your tools: a siphon, algae scraper, and a bucket. Begin by turning off your filter and any heaters to protect your equipment. Use the siphon to remove debris from the substrate, and scrape algae off the glass with the scraper. After cleaning, perform a partial water change and test the water quality to ensure a safe environment.
Common mistakes include over-cleaning the filter media, which can harm beneficial bacteria, and neglecting to rinse equipment in tank water. Always handle your fish gently and avoid sudden changes in water parameters to keep them healthy.

FAQ
How often should I clean my aquarium?
You should clean your aquarium every 1-2 weeks, depending on fish load and plant growth. Regular maintenance helps prevent algae buildup and keeps water quality stable. Don’t forget to perform a partial water change during each cleaning to refresh the tank environment.
What is the best way to clean aquarium decorations?
To clean decorations, remove them from the tank and rinse them in warm water. Avoid using soap or chemicals, as these can harm your fish. Scrub with a soft brush to remove algae, then return them to the tank after rinsing thoroughly.
Can I use tap water for cleaning my aquarium?
While you can use tap water for cleaning, it's important to let it sit for 24 hours to allow chlorine to dissipate. Always use dechlorinator if you're adding tap water back into the tank. This protects your fish from harmful chemicals.
Is it necessary to remove fish during cleaning?
Generally, it's best to keep fish in the tank during cleaning to reduce stress. However, if you're doing a deep clean or handling decorations, use a net to gently move them to a temporary container. Always ensure the water conditions remain stable.
What should I do if my fish are stressed during cleaning?
If your fish show signs of stress, stop cleaning and observe their behavior. Make sure the water parameters are stable and provide hiding spots with plants or decorations. Reducing noise and sudden movements can also help calm them down. A good habit is to finish with a quick reset/cleanup so the next session starts smoothly. That prevents repeat issues and keeps performance consistent over time.
