Before I go into any more details I just want to say that I'm sorry I've been posting so many threads, I just have a lot of questions I guess

Anyways, I've had my divided 15 gallon with the fish in it for about 2 weeks now, and I'm just curious as to how I do a water change. I have a Aqueon QuietFlow 20 filter and the tank only houses 2 fish, the middle section is empty to act as a "buffer zone."

How much water should I replace in a water change and how often? Thanks

Siphoning out the amount of water you want to change with a gravel vacuum would be best, that way you can take out the water while cleaning their gravel. Then pour the new water into the center section to reduce the amount of disturbance to your fish.

I would do two 50% changes a week(if it is not cycled), and one 50% change a week once/if it is.
You would use a gravel vacuum to clean the gravel and take out water, if you didn't already know! :-D
