Approx how many pounds of these to fit in a 10 gallon fish tank?
Answer by ChewyDec 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.

What is the approximate size of the pebbles?
Answer by ChewySep 29, 2019
Exotic Pebbles Natural Washed Black Gravel may vary in size and shape due to the natural composition of the pebbles and direct sourcing. They will measure approximately ⅜ inch - 1 ½ inches.

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.

They look good to me!

I really like these stones in my fish tank. They aren’t black but more of a deep gray and yes a couple of the stones are brown. I rinsed these when I got them and it still fogged up my tank but that went away after a night. The stones are bigger than traditional tank gravel that I see in most tanks but I think that’s neat. The bag was smaller than a 20lb bag at the pet store because these stones are larger and therefore heavier. One bag took care of one ten gallon and a half of another but I had a small bag from a pet store of those neon glow rocks to make my little girl happy- I don’t think it would completely do two ten gallons unless you prefer less gravel at the bottom of your tanks.

love love love these pebbles!

these look soooo good. i put these in my aquarium because im not too fond of how gravel or sand substrate looks and i am very impressed. it looks so clean. there were two white pebbles in my bag but i actually like it and think its cool. these are also great for anchoring tubing and plants! i highly recommend this.

Not happy at all

Not happy at all. I ordered the bigger stones and recived the small pebbles. 1 bag was busted open. Not a happy camper at all.

These are more like small rocks instead of gravel.

If you get these for your 55 gal. tank, you need at least 3 bags, more if your tank is larger. I use an under gravel filter and 2 HOB powered filters. They look good in the tank...

Not Black, but pretty

They aren’t black, but rather a darker grey. Not issues with broken ones. We did wash before adding to the tank. We like the look!

Nice Rocks, Bad Packaging

I really like these rocks they were exactly what I was looking for. However, while washing off the excess dust I got a few cuts. There was a rather large piece of glass I hadn't seen in the hiding in between the rocks. I was surprised. I wished they took more care in assuring such harmful substances don't make it to their final product. The rocks themselves are very nice.

Nice, but they’re not black

These rocks are nice and smooth, what I was looking for to be kinder to my cory cats’ barbels, but the rocks are definitely not even close to black, so I just can’t give them five stars. The stones are larger than your average aquarium gravel, which is kind of a neat aesthetic, so that’s cool. I just really really wish they were darker. The photo was taken under my LED tank light on its lowest setting.

Be Prepared to Wash

They say washed, but they were covered in dust and so were all the items in the box. Washed these in small batches in a cullender in the sink and found pieces of glass and wood mixed in! They look good now that I've cleaned them all, but I'm lucky I didn't get cut - and think what may have happened if I put my fish in without sorting them first!

They're grey

Maybe I just got a bad batch... my pebbles are grey, not black. And they are rather dull, not at all shiny like the picture shows. Disappointed.
