Questions & Answers

51 Customer Questions

How big of a tank does one brick cover?
Answer by ChewySep 02, 2017
One compressed brick will expand to make 7 to 8 liters of substrate. It depends on the size of your tank but on average one block can cover a 10-15 gallon tank with 1 inch depth.

How many bricks do i need for a 40 gallon tank
Answer by ChewyMay 24, 2018
One x 3 brick value pack will suffice for your tank as one block can cover a 10-15 gallon tank with 1 inch depth.

Does it need to stay damp for bearded dragons?
Answer by ChewyOct 10, 2017
For a bearded dragon this substrate should be kept dry. A damp substrate will cause your terrarium to become too humid and can lead to respiratory disease in your beardie.

Does this substrate run any risks of being flammable? Specifically with an under tank heater
Answer by ChewyOct 13, 2017
Although this product is able to withstand heated temperatures, its high cellulose content makes coconut fiber particularly liable to catch fire through external ignition. Therefore, protection from sparks, fire, naked lights and lit cigarettes must always be provided.

Good Stff But...

I have used this for many years for my humid loving reptiles. During the last couple of years though moths have become a huge problem. They are in the fiber somehow and when you wet it it wakes them up or gets the eggs hatching. My basement is loaded with them. The solution is to soak the bricks outdoors so the moths don't get loose in your house. Or if you can, leave them outside for the winter to kill the moths off.

Eco Earth coconut fiber

Not new to Eco Earth coconut fiber and this is doing exactly what I needed it to do. Using this as part of the substrate in a roughneck monitor enclosure.

Best Substrate

Love this substrate for my ball python. We freeze it when we first receive it to kill any mites that may be in there, and then add water until it’s the right texture. Chewy makes autoship really easy so we love using them for all of our pets!

Perfect for my cresties

I have 6 crested geckos in a big tank and a 3 pack lasted me months. It's ideal for reptiles that thrive in the forest, and burrow. It doesn't harm them and my geckos can find their live feed through it. Gonna buy again when in stock. :)

not the best for beardies

it said this product was good for beardies, but since it needs to soak in water before going in the terrarium, the humidity was way too high and i had to take it all out. my beardie was too interested in it and kept licking to smell it, and probably ingested a small amount, but it’s indigestible and can cause impaction. i do not recommend for bearded dragons. probably a better product for tropical reptiles.

Good product. Just wish it could be bought in larger quantities for us that use it in bulk.

I’m amazed

Great product, fast delivery. I usually get the same thing from the pet store, for my composting toilet. The problem with the store option is that I can only buy up to three bricks at a time due to store shelf availability. I plan on using this method in the future

I got pork chops , he's a guinea pig

This for his bedding and he seems to like it, had to make sure that after I absorbed it in water and it soften, to let dry out before placing your small furry pet on it.

No longer a Value

Price is 4x what it was. No longer a good buy. Turned off my autoship.

Okay but not consistent

These are good for the price but unfortunately in a 3 pack of bricks , the three bricks aren’t always consistent. What I mean by that is that sometimes one brick makes a lot of substrate/bedding for the tank and then you’ll randomly get a brick that makes noticeably less substrate than the others which is an issue because I end up with overly hydrated bedding that is more suited for a swamp environment than it is for my snake. I’m going to have to resort to weighing each brick individually before adding water, that way I don’t over hydrate
