[rpcruz28]

Hi guys, new here.
I had a tank many years ago and Im buying this kit thats is affordable:

I remember using gravel but I can see many people using white sand that looks very nice and cleaner.
So, which kind looks best and how much I need for this tank in particular( how deep I should use to avoid problems).
Also I would like to keep some snails and shrimps as cleaner(and also is cool)
Any suggestions about type of plants? I saw this aquarium and I liked, can you tell me which type?Do I need use any filter under the sand?

You would need about 20# pounds of sand. You don't use any kind of filter under the sand. Not sure what other things you are asking about...
