Approx how many pounds of these to fit in a 10 gallon fish tank?

Answer by Chewy • Dec 12, 2019
The amount of rock depends on how deep you would like the the rock in your tank. Multiply the length by the width of the tank and divide by 19. This will give you the amount of gravel needed for a depth of 1 inch.

Large size gravel my gold fish can't swallow.

Larger poops get trapped better.

NOT washed

I washed these again before putting them in my tank and thank goodness I did. The water was so nasty I rinsed them about 10 times and then let them soak in water and re-rinsed then. When I did put them in the tank it made the water dark and cloudy for a couple of days.

Awesome!

This gravel is fairly large and definitely not black. More of a dark charcoal color. My mystery snails have no issue nor does my King betta. A little harder to clean

This gravel is fairly large and definitely not black. More of a dark charcoal color. My mystery snails have no issue nor does my King betta. A little harder to clean as it is a heavy pebble. I really like the way it makes my decor stand out in my 20 gallon tank.

Not truly black in color. I thought when I saw this product online that the stones would be a glossy black, but when I took them out to pre-wash them they were more dark grey.Of course they look darker when submerged in water, but they still appear grey.If your looking for a glossy black gravel, this is not what you’ll get. Nevertheless, I still like the stones and it looks great in my aquarium.

almost perfect

Let me start off by saying these pebbles are exactly what I've been looking for as a beautiful natural alternative to the typical aquarium gravel. The 20lb bag perfectly

Let me start off by saying these pebbles are exactly what I've been looking for as a beautiful natural alternative to the typical aquarium gravel. The 20lb bag perfectly covered my 20 gallon long tank. The pebbles are smooth, the perfect (not too big or small) size, and look amazing in my tank! Now the down side. After reading some reviews of the gravel needing to be prewashed (which I would have done regardless), I took extra care in not only soaking them over night but thoroughly washing them by hand in a strainer for several minutes in small batches. After setting up my tank, I added the water and let it settle for 2 days because the water was very cloudy. Despite the time, new filter, and water treatment the water never cleared up. leaving my tank with a dreary foggy look to it. So after several days of work, I'm now going to have to drain the tank and refill it. Hopefully after all this it won't be cloudy, because I really like this gravel and don't want to waste anymore time or money on getting new gravel. I'll update after the water change.

Not black but still nice

I really like these rocks. They are not that shiny black but they look beautiful in a fish tank. They look natural. I am happy with the purchase.
