If you want sand just for looks, put whatever sand you think looks the best. Me, I like my sand bed to perform filtration, besides looking nice.

Fish-only tanks tend to accumulate Nitrate, which can encourage algae growth. A deeper sand bed can accommodate both nitrifying and de-nitrifying bacteria, which reduces Nitrate. It doesn't even have to be very deep, with a fine sand. It's a thought.

Good luck with your tank redo!

As many naturalists and environmentalists have suggested, we should set aside our arrogance,
our desire to conquer and control everything, and walk hand in hand with Mother Nature. -Walter Adey
