Water change after cycle?

[MikeyTankx]

Hey everyone! I’m brand new to the aquarium hobby and super excited to finally be getting started.

I just finished cycling my first tank — a 15-gallon — in about 2 weeks. Now that it’s cycled, do I need to do a water change right away? And if so, what percentage would you recommend?

Also, will the tank be okay sitting empty for about one more week until I can get my cleanup crew in?

Any advice is greatly appreciated! Thanks in advance!

I doubt it needs a water change. Doing so is, I believe, a carry over from when folks wanted nutrients very low and/or cured live rock with lots of die off.

As long as you got a powerhead and a heater going, the tank can hang out without any residents.
