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.

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.

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.

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.

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.

Love the Color, Not so much the tiny rocks

I bought the white rocks when I decided to redecorate my fish tank. First of all my fish tank looks so nice, the white really brings the whole thing together. Seem like decent quality rocks. I sanitized them with boiling water before putting them in the tank. No paint flaking. I did notice a lot of dust when I strained them after rinsing. (you should always rinse and strain new rocks bc the dust is very bad for your fish to breath in) That wouldn't have bothered me so much if it was only dust. However, a pretty big portion of the rocks are TINY. Like almost sand. I lost a good 1/4 of the rock when I strained them. (I used a cullender with very small holes). Waisted a good portion of my rocks. and almost destroyed my sink (I noticed it wasn't just dust coming out and managed to quickly block the drain. cant imagine what it would have done to my sink if I hadn't caught it so fast) and made a huge mess for me to clean up- scooping handfuls of basically course sand out of my sink. If I wanted sand for my tank I would have ordered it- I wanted rocks. Disappointing. But the quality of the remaining rocks and how nice my tank looks with them kept me from giving them 1 star.

I rinsed it before putting into my tank and the water came out bright red. I thought maybe it was just the initial rinse so I washed it several more times with the same result. I put it in a bucket so I could move the gravel around to rinse it outside of the bag but the water was still coming out red. After letting it sit for a few minutes I thought the color would settle, instead it stained the bucket. I would not trust using this with fish unless you want everything stained the color of the gravel.

Turned a plastic bowl black

These were really strange aquatic rocks. I rinsed them before putting them in a tank and the water ran grey for a very long time. The bowl I used to rinse them was stained black (it was plastic) I didn’t use them in my tank because I couldn’t get the water to run clear

I had to call chewy because of how bad it was. I ordered the black rocks, it stained my hands, tub and turned the water black no matter how many times I rinsed it. It smelled very strong of spray paint. Thankfully I called and they gave me a refund.

Bright & Bold

The gravel was exactly what I ordered online. Really brightened by tank. Recieved order before delivery date.

This will destroy your tank water!

I have rinsed this over 5 times. It’s stained my hands, my tub, and my pitcher. Do not put this stuff in your tank. The pebbles are losing the color and the water still looks like fruit punch. Thankfully the chewy staff is amazing and help me get it all sorted. Just don’t waste your time on this product.

Good Gravel

This gravel is excellent, HOWEVER, the packaging, the plastic bag that it came in, opened up inside the delivery box. The plastic bag needs to be stronger.

A new look

The (red) gravel is delightful. So clean and natural, he likes to sit at the bottom. It collects slime and debris for thorough cleaning. Changes the water color for fish peace- he is red also. If you have a tube to hide the sand covers; he doesn’t look sick! Add shells to your bowl to ensure safe egg laying.
