depends on the diameter of the gravel.
the level of gravel should not be too thin or too thick, say on an average 2-3 inches of gravel should be the ideal level. In my opinion 30-35 kgs of gravel will be sufficient.

55 Gallon aquariums are only 12 inches deep, so in my tank I got away with 40 lbs.

The amount of gravel you use is entirely up to you.

I am not sure what type of aquarium you are referring to here. A standard 55g tank is 48l x 12w x 22d. I dont know of any 55g tanks that are only 12in deep unless they are 8ft long. Maybe you mean a 20g long? These are only 12in deep. The general rule for substrate is 1-2pds per gallon depending on the depth of substrate you want. Deeper gravel is much more difficult to clean because it allows any food or debris to fall down between the rocks & become trapped leading to water quality issues.

The general rule of thumb is more of a guideline to go by. Substrate serves as two purposes. The first is to provide additional space for bacteria to grow in. The second is purely cosmetic.

All I'm saying is that in my 55 gallon tank, 40lbs served its purpose covering the bottom of the tank. Putting in 110lbs of substrate would be ridiculous.

1 to 2 lbs of gravel per gallon. It will say on the bag you buy how much you need for what size tank and for the size gravel.

You need at the least 1 pound of gravel for every gallon of water i got 55 pounds for my 55 gallon aquarium.

I totally agree with you!! I am looking at a 60 gallon tank and i CAN NOT see adding 120 pounds of gravel on top of decor and water and plants and fish. If I were to add 120 pounds of gravel, I would not have room for the rest. And I would end up cleaning the tank EVERY SINGLE DAY DUE TO IT TRAPPING SO MUCH and becoming toxic to the fish. I think that they say that you need that much gravel just so you buy more gravel than you need.

I have a 55 gallon tank and it's much deeper than 12 inches. I'm only using 25 lbs.of gravel. Two lbs. per gallon would be 110 lbs. of gravel, that's crazy.

I have a 35 gallon, and I have about 20 lbs of gravel. Easier to clean! Kinda hard burying the plants bases all the way...

It is a math equation.... Length of tank x width of tank x desired depth of substrate

deep is referring to the measurement of front to back (edited by administrator)

Due to the fact that 1) You do not know me 2) That is not me sounding harsh and neither is this 3) A person thanked me for my help on this thread 4) You must be used to other forums where being extremely rude is common because that is not THIS forum. I am thinking you may be having a very bad day.

If at any time you would like to start over feel free! Now you have a lovely evening.

Honestly I agree with you. I only have added 60 lb of gravel in my 55 gallons tank. 2 lb per gallons is overly excessive. I myself don't want to over do it. You don't want cleaning it over and over just because your gravel is deeper than normal and disturbe the fish in the process more often than you should.

You need to care as it's a 3 yr old thread and has already been dealt with. Answering these old threads just pushes newer more urgent questions down.

I have a 55 gallon tank. I think it's just preference. In mine, I don't like very deep gravel. I keep mine maybe an inch and. Half. I think I used a 20 lb bag

I would say mine was more like 30 lbs. it's enough to make an inch and a half. I personally, do not like deep gravel. It causes a mess so I keep it just enough. It makes it easier to clean as well. That's just my preference, however.


I'm going to switch to sans substrate just have not gotten to it yet.
