water changes

About how much and how often should i change the water in my 37 gal tank?

1. What filtration method are you using
2. How much livestock does your tank support
Normal going rate is 10% per week.
If you have a sump then you can afford more bio waste because you have more surface area for biological filtration. Does more stock could be kept depending on what you keep and their environmental needs. (space etc.)

4 gals per week should do the trick.
How is your evapuration rate? if you top up often it also helps as long as your parameters stay stable. but dont mistake topping up with a water change. id still stick to atleast 3.5 to 4 gals per week:thm:
