In a 10g filtered tank-weekly 50% water changes along with gravel vacuum in all area that can be reached without moving anything in the tank (like decoration) or disruption of live plant roots and the filter media needs a swish/rinse in old tank water with a water change 1-2 times a month and when the water flow slows to get the big pieces of gunk off to maintain good water flow 24/7-would be needed for the life of the aquarium or regular maintenance
Usually on filtered aquarium with proper maintenance- will not need 100% or total tear downs unless you have high nitrates (over 80ppm) that you can't get under control with regular vacuuming/filter media cleaning.
This is based on proper stocking, not over feeding and removal of uneaten food in a cycled, filtered 10g aquarium with or without a couple of live plants to maintain water quality healthy for aquatic life.
During the cycling process without water testing-for the first 4-8 weeks-water only change of 50% one time a week and 50% with vacuum a week may be needed to keep ammonia under control until the beneficial bacteria have colonized
With water testing-50% weekly as described above and 50% water only changes with any water pram readings of 0.25ppm of ammonia/nitrite until you have reading of nitrate of at least 5-10ppm without ammonia/nitrite readings between water changes
You know you are cycled when your water prams read:
