How many bags do you need for a 20-gallon long tank?

Answer by Chewy • Jul 15, 2021
Determining how much substrate to buy for your aquarium depends on the size and shape of your tank, as well as the depth of the substrate bed you wish to achieve. In general, we suggest 1 pound of substrate per gallon, to achieve a 1 inch bed or 2 pounds per gallon, for a 2 inch deep bed.

Hi! I noticed this is a coated substrate. Does the coating come off? And if/when it does, is the coating and underlying rock safe for shrimp? Thank you.

Answer by Chewy • Apr 05, 2019
The 100% acrylic colorfast coating is non-toxic and won’t foul your water or impact your water chemistry.

can these pebbles be used for a beta fish tank?? and does it matter what color

Answer by Chewy • Jun 13, 2021
This gravel is suitable for fresh & saltwater aquariums, ponds and terrariums. It should work nicely for your various fish species.

How many shades of blue are in the marine blue bag?

Answer by Chewy • Feb 04, 2019
Every color the gravel is available in is intended to be a single shade. However, some pieces may appear lighter or darker due to the process of color coating the gravel.

Great Gravel Purple Passion

I got the purple passion and it’s purple! If you’re looking for a true purple color then get this!! I don’t know why it says Turquoise on the picture shown. But

Black and Blue Aquarium Gravel - Suggest you wash before use

I purchased two 5 lbs bags of Black and Blue Aquarium Gravel. Both are good. I did wash them both using a strainer and moved the gravel around. I had to wash

I purchased two 5 lbs bags of Black and Blue Aquarium Gravel. Both are good. I did wash them both using a strainer and moved the gravel around. I had to wash the blue gravel 4 or 5 times before it stopped giving off some color. The black grave l washed 1 or 2 times.

Hmm

It was okay-quality pebbles. One bag was arrived as ripped and there are a lot if tiny pieces mixed in, almost like a thick sand

Please pay attention

I screwed up by not reading all of the details. I bought 4 bags and can't use them. I need a bed for my saltwater tank. I can't use these in saltwater. Now I'm stuck

I screwed up by not reading all of the details. I bought 4 bags and can't use them. I need a bed for my saltwater tank. I can't use these in saltwater. Now I'm stuck with 2 unopened bags that I can't use. The other 2 bags, I opened and will by tossing them outside. I'm sad.

Off color

The pink gravel was a different shade than what was shown in the picture. The quality is still good just a darker brighter pink.
