Answer 1

A good rule of with any aquarium is to do a 20 to 25% water change every week.

An easy way to judge the percentage of water you have removed from your tank is to measure the front glass from top to bottom, then divide the height by four and remove the answer in inches for 25% or by five for 20%.

For example with an aquarium that is 20 inches tall you would have to remove 5 inches of water for 25% or 4 inches of water for 20%.

Good luck.

Answer 2

As a general rule you should change 25% of the tank once a week. While it's true a larger tank can be and usually is more stable chemically than a small tank, it's also true that a large tank usually contains more fish or larger fish so the volume of water to amount of fish is similar. Therefore water change percentage and frequency should be similar.

Answer 3

Generally whenever you change your tanks water, you only want to remove 25% of it per change. With smaller tanks, you may need to change it once a week, but since you have a 75 gallon tank, you won't need to change it that often. Plus, they make a lot better filtration systems for the bigger tanks.
