Are the granules smaller then regular gravel? Is it little more corse then sand?

Answer by Chewy • Jul 15, 2022
The typical granule size in this gravel is 1 to 2.5 millimeters.

how many bags would be needed to fill the bottom of a 40 gallon breeder tank

Answer by Chewy • Sep 12, 2022
This gravel has a substrate density of 100 pounds. The general rule is 1 to 2 pounds per gallon, but if you want to be more precise, you can use the following equation. In inches: Length x Width x Bed Depth Desired. Then divide by 1,728. Then multiply by the approximate substrate density (100 pounds, in this case). Your answer is how many pounds you will need. One would need about 35 pounds per inch in a 40 breeder.

Does this help promote life of plants ?

Answer by Chewy • Jun 22, 2023
This substrate is not intended to promote plant life or plant growth. This gravel may be used on top of a nutrient-rich substrate below.

Answer by Chewy • Jun 25, 2023

I have this in all 12 of my current tanks. It's the PERFECT grain size, coarser than beach sand, but substantially finer than commercial aquarium gravel, plus it's absolutely beautiful, and very consistent bag to bag, because I've been buying it over a period of years. EXCELLENT PRODUCT!!!

We received both boxes and o e of the boxes again inside the bag was open at seam and all over the place. I would suggest getting a different delivery people as I watched on my camera how they handle the the package and they just throw them. Or maybe you should put on the box handle with care or fragile just a suggestion.

Natural smooth texture

Very nice look, wanted darker mix initially, but this was the better deal for the price. Took a lot of cleaning before I could actually place in tank. Took about 24 hours for tank to go from murky to clear again. Seem pleased with gravel so far.

Perfect alternative to gravel

I wanted a substrate that is easy to clean, and also easy on my little corydoras whiskers. This is the perfect balance. It’s not too sandy, but the pebbles are small

I wanted a substrate that is easy to clean, and also easy on my little corydoras whiskers. This is the perfect balance. It’s not too sandy, but the pebbles are small so they are gentle on bottom feeders. Be sure to rinse and soak for several days if you don’t water your tank to be cloudy.

Beautiful small gravel

This gravel is so pretty. It’s lighter than in the picture. I’d say it’s mostly white, with some tan thrown in, and a few black stones here and there. It might show

This gravel is so pretty. It’s lighter than in the picture. I’d say it’s mostly white, with some tan thrown in, and a few black stones here and there. It might show more like the picture if you have a warm tone aquarium light. Small gravel but not sand. Easy to vacuum and it doesn’t get sucked into the waste bucket like sand does. My juvenile goldfish love picking through it.

Beach vibes and so beautiful

I have kept aquariums for years and this gravel is stunning! The pieces are tiny which almost give it a sand-like appearance. Some of the pieces appear to be translucent

I have kept aquariums for years and this gravel is stunning! The pieces are tiny which almost give it a sand-like appearance. Some of the pieces appear to be translucent (almost like a sea glass). There are lots of pretty beige and white tones.

Everything in stock at that the local stores was either too large or too angular or not the right color. I was looking for something slightly larger than sand and a natural color. This was juuuust right. This struck a wonderful balance. There are some larger grains (let's call them accent grains) that gives this gravel a perfect aesthetic. Don't hesitate to purchase this lovely product.

Beautiful ground cover

I use this as ground cover in pots around my cactus and succulent plants. Beautiful and less expensive than buying at a nursery.
