Can I use this in a Betta tank?
Answer by ChewyJun 20, 2022
This substrate is safe for all aquariums including Bettas.

How much is needed for a 10 gallon aquarium?
Answer by ChewyApr 05, 2022
The Peace River substrate weighs approximately 100 pounds per cubic foot. Aquarium sizes vary, but as an example, in a 20 gallon tank that measures 24 x 12 footprint, a 20 pound bag would give you about 1 ¼ Inch bed depth. A 5 pound bag would just cover the bottom to about ½ of an inch.

It says freshwater tank but the description says brackish and marine. Is it for all three.
Answer by ChewyAug 24, 2021
This substrate is suitable for freshwater, brackish, and marine aquariums.

Great substrate!

Great substrate for bottom dwellers. I needed to switch to a finer substrate when I got Corydoras, but I didn't want traditional sand because of how difficult it is to vacuum and how it can stir up easily and clog filters. After searching around I was excited to find this type of sand. It's sort of a cross between gravel and sand, and very smooth. It doesn't cloud up, is easy to vacuum, easy to grow plants in and my Corys and Pleco love it! The natural colors are beautiful in any aquascape.

Grains larger than advertised

I do like this substrate, but the description should be corrected. I require specific sized grains for my use (not aquariums), and this is not the 0.25-1mm as in the description. As you can see in the images I uploaded (centimeter side of ruler), the grains are more like 2-4mm on average. An occasional piece reaches 5mm, but not much more. An estimated 2-3% fell through a 1mm seive. There was minimal organic debris that was easy to wash out (floated) after 3-4× rinsing, less than 1/2 teaspoon in a 5lb bag. No significant dust or odor that I noted. I can still use this substrate for a slightly different purpose and am not unhappy with it, but the description is misleading. **Either uploaded images do not appear in previews of posts or I am unable to post a photo, either in the app or on the website, despite photo meeting size requirements.

Absolutely fantastic!

I was concerned that the pieces were too small when I first received it, thought it would be difficult to deal with (like sand) but it's the opposite. This is the best gravel I've ever used. I have an algea problem and usually by week 2 my gravel is covered in it but it wasn't. Not sure why but I'll take it! Also thought it would clump up when I put it in but it fell into place beautifully and evenly. Even when I cleaned it up it was extremely easy to move around and even out. Also it just looks beautiful! I highly recommend this.

Nice alternitive to sand

I wanted to get some bottom feeders for my tanks but have gravel substrates. I did not want to use sand due to problems years ago keeping the sand clean. This is a great alternative to sand. Very small particles and very smooth. It does need to be cleaned prior to use. My new loachs love the feel (I didn't ask them but they seem happy). Even better is the easy vacuuming.

Naturally pretty!

Love the way this substrate looks in my tank! Arrived quickly and didn’t have to do much rinsing before I put it in the tank.

Love this!

This substrate is perfect for my tank! I decided to re scape my aquarium and this looks wonderful, will buy again for my other tank as well! I also ordered a small bag of sand and they work so well together!

CaribSea peace river

Absolutely the best substrate I've used for multi species tank setups. Great for pygmy corydoras and standard sized corydoras, no wear to fish barbells, smaller grain, but not sand. Amano shrimp love it also, easy to pick through and scavenge, food doesn't fall through. Great for planted tanks. I have used this exact substrate in 4 aquariums now and am very happy with it.
