Water changes

[robvia]

Is it better to do a smaller water change more often or a larger one less frequent?

I am setting up a 90 gallon tank. Would it be OK to do a 5 gallon change each week, or a 10 gallon change every other week?

Pros and cons to each?

Thanks,
Rob

Smaller changes more often is definitely the key! I do 5% or 10% water changes each week and I haven't lost a fish in years in any of my tanks. I find doing water changes relaxing and it gives me a chance to check everything over really well including the fish.

Best of luck,

John
