Re: First water change?
Can't remember if you mention elsewhere, but do you have fish in your tank or are you cycling fishless? If fishless, no need for a water change until after you cycle.
If you have fish, you won't mess up the cycle by doing a water change. It continues no matter. Doing water changes in general make it go slower, but it is necessary if you have fish in the tank already to keep them alive. However, I would not do water changes until you detect ammonia in your tank. It took me nearly 4wks to register anything on my 75g tank.....but, I had a low number of fish (for my tank size) to start with and was doing water changes every 2-3 days.
