Tank moving plan...

[kien]

The sand is kinda preference thing. I've used sand that's 4 years old that I just rinsed with each tank change but recently I added some new sand for the extra sparkly look of a new sand bed. Keep in mind that if you use new sand you will likely get a diatom bloom on the sand bed. Nothing to panic about tho. Unsightly but you can easily wait it out. If you want to save a few bucks using the old sand is fine to.
