People constantly ask me how much substrate comes in various packages from various sources. So let's take a look.
Here are a couple of my favorites. One is overpriced, the other isn't. I'll let you figure it out for yourself.
Each 2kg bag of the Shrimp Sand is $20-$25.
Each 5.4kg bag of Azoo is $20-$25.
Azoo is lighter than Shrimp Sand so you get easily 4-6 times as much product for your money.
Two bags of UP Aqua Shrimp Sand **might** be enough for me to line the bottom of this tiny tank. A bag of Azoo will cover a 20L with ease.
Not trying to review vendors, not trying to say one is better than the other because they both have their strengths and weaknesses. Just showing you what you get for your money.
