What is 25% of one gallon?

Question

it's time to do a water change

can you tell how many cups it would be?

Answer 1

a quart

Answer 2

its 946.352946 milliliters

which is 4 US cups exactly

but why do you need to change water in a one gallon tank

as no fish is suitable for a tank that size not even a betta

or

are you just going to times the 4 cups by the amount of gallons your tank holds

good luck

Answer 3

I cannot give you a exact quantity of water but if your tank is one gallon as I am assuming just take out around a quarter of the water, besides if it is a one gallon tank you are better off cleaning the whole thing once every 2 weeks
