Let's talk substrates

[poison]

ADA soils are in fact safe to use in a frog tank, BUT, they release a ridiculous amount of ammonia while the tank cycles. You should cycle it in an aquarium, monitoring levels and doing constant water changes until the tank cycles then i would transfer it to a viv.

For what it is worth, i use a soiless soil mix used for hydroponics growing and a layer of cocofiber in all my tanks and my plants love me for it. Also, all soil becomes "bio-active" over time.Like an aquarium denitrifying bacteria are present in soil. It's how soil breaks down nitrogen so plants can use it. Bio-active soils are just seeded with bacteria, nothing more.

Though bacteria is the main part of bioactive substrate they're are also other critters crawling around in it. Microbes, substrate mites and if you choose too add them in then earth worms, isopods and spring tail (though there is a species thast usually makes its way into my enclosures withot me adding them).

My cornsnake enclosure has been up and running for over a year, never once cleaned (other then spot cleaning obvious waste matter). It smells nice and fresh to this day. Heres a nice read http://www.geckotime.com/bio-active-reptile-substrate/ You can also read more about in "The art of keeping snakes" book.
