1.0 out of 5 stars triple check the contents!
Reviewed in the United Kingdom on 26 April 2021
I ordered a 4L container and it arrived unsealed which I believe is normal, checked at my local aquarium store and all theirs were not sealed either.

When I opened the tub I noticed a lot of ceramic rings (see images), this worried me so I emptied the entire tub. I found about 5 pieces of actual pumice and the rest was quartz gravel!
It looks like someone else had this tub, took out the contents and sent it back to Amazon for a credit with random quartz gravel in it.
The zoomed-in photo shows one piece of pumice in the centre and the rest is just normal stone gravel!

Anyone without experience would have put this into their filter and it might of done the job but it wouldn't help the nitrogen cycle as much as actual Matrix would.

Be very careful and tripe check the contents before using it in your Aquarium!
