Aquariums reward small regular attention and punish occasional heroics.

Weekly

A 20–30% water change with conditioned water at matched temperature. Syphon the substrate as you go rather than as a separate job.

Rinse mechanical media in the water you have just removed. Check the heater reading against a separate thermometer.

A full water change, a scrubbed filter and new gravel on the same day. That is a reset of the biological colony, not a clean.
