Questions & Answers

12 Customer Questions

How many bags do you need for a 20-gallon long tank?
Answer by ChewyJul 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.

How many shades of blue are in the marine blue bag?
Answer by ChewyFeb 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.

can these pebbles be used for a beta fish tank?? and does it matter what color
Answer by ChewyJun 13, 2021
This gravel is suitable for fresh & saltwater aquariums, ponds and terrariums. It should work nicely for your various fish species.

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

Nothing dyed or died!

Got 5 bags of the Marine Blue to freshen up my 30+ year old gravel. Don't believe the horror reviews that are on here. It didn't stain my rinse bucket or my hands or turn my tank blue. My fish are doing fine and like the new color. Sure it takes several rinsing's before your rinse water will run clear. Big Deal. This product has been around for a very long time and for a reason. If you want to add color to your tank, get this. Also no one can touch the price CHEWY gets for it.

Not dusty at all!

Before I put it in my tank I washed it and expected it to be super dusty and it wasn’t at all!! My betta looks amazing with this gravel! Definitely recommend it. This filled up my 5 gallon perfectly!

Garbage, literally

Yep, I had to throw it away. I bought the marine blue color and I rinsed it 3 times and even let it soak for hours and the color still bled. My hands were blue! There was no way I was going to trust putting it in my tank. I wishI had read reviews before I ordered it.

Difficult to rinse

Cannot recommend. I've been rinsing and soaking the 20 pounds for over a week, and the rinsate is still blue. My hands are blue afterward. I'm wary.

Everything was ok except....

The 9 5lb bags of aquarium gravel was packed ON TOP of the filter!!! And one bag of gravel had a hole in it! Have they no common sense???!!!

Great gravel!

It looks great! Be sure to rinse thoroughly. There is lots of excess dye and small pieces that float and get into the filter or the fish confuse for food.

Do Not Recommend

I am no aquatic expert whatsoever, but the dye they used to color these rocks seems a bit unsafe. We chose the red and by the end of day 1, the water was super cloudy and starting to turn red. We had to change the tank water every other day until I was able to get new rocks and got them out of there permanently. Will not try color again!

It’s a bleeder!

This sand like gravel BLEEDS so much I had to wash for a good hour, stained my hands and the bucket. Always wash until water runs clear!! It does take a while but once the water is clear I’ve had no issues with the gravel bleeding inside the tank and I can grab it without it staining my fingers so if your up for a good long gravel soak and wash I say buy this one! Works well in both my tanks with no bleeding or staining issues. My only issue is when I clean the gravel it’s so sand like a little bit tends to suck through the vacuum siphon.
