Answers:

It's a pretty small tank which is fully stocked, albeit without huge waste producers. I would recommend a weekly 20% water change/gravel vac should do it. I have small tanks myself and they definitely benefit from weekly changes. The smaller the tank the quicker the bad stuff will build up!

well usually they say once a week is best for a water change, obviously not the whole tank, we usually do a quarter of the tank.

they say you should take out 25 percent of the water once a week...as long as ur filters are good you should be fine..dont forget to add appropriate amt of water conditioner every time you replace water.

YOU CAN DO WATER CHANGE ONCE IN 3WEEKS.

20% weekly is perfect
