Water changes on mini-tank

neonk

Hi,
If I'm running a mini-tank about 1.5 gallons with a filter, how often do I need to do water changes when the tank has cycled?

not very often with your circumstances mabey once every 3 weeks and take out the rocks rinse them and take out and replace 25 percent of the water
