100% NATURAL. Every owner of underwater pets knows that decorations and aquarium substrates not only look nice, but also affect the environment of our fish. That is why it should be ensured that most of them are natural. Our sand is not artificially coloured. You can rely on our experience. Buy sand from companies that specilise in aquarium substrates.
This substrate ensures very good rooting and rapid growth as well as attractive appearance of plants what can be seen on the pictures in gallery. Product used in agriculture as a natural fertilizer supporting plant growth. In an aquarium with strong light, our substrate can have a slightly graphite shade that gives an even more natural look.
Before use, we recommend that you only pre-wash the substrate, please do not do this thoroughly because it is a never-ending work. After pouring out the substrate into the aquarium and covering it with water, a natural cloudiness may occur, which will disappear very quickly after starting the filtration.
In order to create a 4-5 cm thick layer of substrate in an aquarium of a given bottom length the following is needed:

A Challenge For All Liberals
Format: Paperback
I thought the book was well-written, impeccably sourced, wide-ranging, and with a thesis that can't help but make you think. Well worth your time.

The history is unpleasant and therefore worth knowing.
It's a wonderfully enlightening history of how European explorers visited, settled in, conquered, and exploited other continents with unparalleled cruelty in the name of power, greed, and their "loving" religion that brought them misery, exploitation and, all too often, abject slavery.

Wonderful History Lessons
I ordered this book to use for a college paper I was writing and found it fascinating. I enjoyed the content and learned much from it.
The history is written in a manner that for those people that either don't read much or don't like to read (yes, there are a few people out there), it will draw you in and make you question the history lessons we suffered through in high school.
