What would be better to use if i were to set up another tank? Or is it just a personal preference?
While this is true, another reason to choose sand over CC is the sand is able to harbor much more life than gravel. There are many kinds of worms and "bugs" that will populate a sand bed but can't thrive in CC. They will process uneaten food and fish waste quickly. You will never need to vacuum an established sand bed. Tank maintenance will be lower.I tend to like live sand a bit better. CC has a tendency to capture particles of food and waste, thus casuing nitrate and amonia spikes. Also, using LS in your new tank will help out cycle time.
