I have just bought a 120L fish tank and need to find gravel for it, roughly what weight in KG will i need?

Looking to set up for tropical fish and am also looking for ideas on types of fish to put in it. Firstly need to find out how much gravel i will need. The tank measures 40ins wide by 12ins deep and 16 ins high.
Answers:
Don't use gravel. Use the little gem rocks. Gravel is much harder to clean and starts to smell after a while. You can get cool stones from any craft store.if ur luck you can find some at the dollar store. You dont have to worry about the fishies eating them or them getting stuck in your filter, plus they are really easy to clean(TRUST ME)..just strain them and rinse with hot water-but cool em off 4 u put them back in.duh!- 120L is like 32 gallons but im positive you wouldnt need 32lbs of gravel.maybe 25 if that. Use your best judgement.

My personal faviorite tropical fishies are Neon Tetras because they are low maintence and very eye catching.. not to mention, the little hot pink ones are so very loveable! But here are some community fish that are beginner friendly:

*Bleeding Heart Tetras
*Bristlenose Catfish (algae eater)
*Banded Rainbow
*Cherry Barb
*Guppy.(easy breeder)
*Swordtails
*Dwarf Neon Rainbow
*Clown Loach

The list goes on and on just be sure not to get Aggresive fish!( I made the mistake of putting my beta fish in with my tank and, even though it was the smallest fish in the tank, it pick on all of my other fishies, killed my little froggie and somehow managed to tear a claw off of my little crab!.BAD BETTA.so i had to put him back in his bowl.by himself.!) When you go to the pet store to purchase your fish ask where the community fish are and explain that you are building a begginners tank and im sure they will be happy to assist you in choosing the perfect fish for your tank. Also i would get an algae eater such as a catfish or snail just to help keep the tank clean!

GOOD LUCK!!
~if this helps, you should buy a fish and name it Nemo.just for me! ;) lol
1 lb per each gallon is what i know.
The weight will depend on what size gravel you desire. A good rule of thumb is get enough to cover the bottom a minimum 2.5 inches deep. This will allow you to employ an underground filter to keep your tank clean. Regular gravel typically comes in 10lb bags, so 12-14 bags are what you're looking at for a 120-gallon long tank.

If this is a first tank for you, I would suggest trying some of the more common, non-aggressive community fish to populate it with. Danios, Tetras, Sword tails, etc. They're hardy, entertaining to watch, and will teach you how different fish interact at different "layers" of the water. Then you can begin planning your other tanks. It's habit-forming.

If the 120L means "liter" instead of "long", convert from the above gallon-based calculation to liters. Or just cheat and make it as deep as your index finger is long.
go to your local pet store they should be able to assist you
one pound per gallon. One gallon is 3.8 L (120/3.8=32 gallons) so you shoud use approximately 32 pounds of gravel
I think you'll fing that Kilograms are a measure of mass which is space taken up.
You have an area of:

40 x 12 = 480 sq in

OR

(2.54x40) x (2.54x12)
101.6 x 30.48 = 3096.768cm虏


Now u need to work out how deep you want it, around an inch?

480x1=480In鲁

3096.768x2.54=7865.79072cm鲁

Now u need to work out the weight of your gravel.
I used the method listed here .
http://www.cardigansand.co.uk/howmuchdoi.

Using metric measurements i got 0.01337184 Tonnes
To convert Tonnes into Kg i times by 1000 as 1Tonne=1000Kg

so 0.01337184 x 1000 = 13.37184 KG

Or worked out using imperial measurements

1*3.33333333*1/250=0.01333333T.
*1000
13.33333 KG

So you need around 13Kg of gravel.

If you do need it to be 2.5 in deep rather than the 1in i have permitted for the answer Then it should be roughly
13 x 2.5 = 32.5 Kgs
u need a pound for every gallon but it depends on what u like i think u should have least 4inch in the front and thin it out at the back u can and more gravel when u want just make sure u rinse it good
depending on the kind of fish you get it may be different, but the general rule is 0.1kg per L of water or 10L water per 1kg
you need about 12kg of gravel
