I wouldn't waste your money on it. I just looked at the product description and can't find what it actually does (apart from everything), or what is in it. Get yourself a bottle of Prime and call it a day. Don't trust anything that claims it "does it all" with "no chemicals." Everything is a chemical and you need a chemical to detoxify chlorine. They also won't release the ingredients. So, without knowing what is in it exactly, I wouldn't actually recommend it because some fish species have sensitivities that others don't. I found a page of someone who corresponded with the company trying to get an ingredient list:
(An email received from the company)
Easy-Life contains earth minerals. No chemicals, bacteria, enzymes or
additional organics. It has a conductivity of about 185 mS (as opposed to
chemical and biological products, which have thousands of mS).
The exact minerals it contains and the way the endproduct is produced, is
our intellectual property. Anybody who would disclose such things with a
product such as this, would be a complete idiot.
