Substrate

I am looking at this substrate as an alternative for bark or chips. I have seen this in a few videos and i thought it looked fine. What do you guys think.

Repticarpet can be an alternative to loose substrait. But it coes with its own set of problems. Nails and teeth an get stuck when hunting o walking about, plus they can harbour harmful bacteria if not washed every time your leo poos. You could littertrain the leo (to a degree) and have 1 corner set up with a litterpan or paper towel squares. Remember when making yur set up, 3 key thngs I consider core elements are try to simulate natural habitats, carpet wouldn't qualify as natural... simple to clean, usually involves a lot of hard surfaces, and user friendly, meaning you're not tearing out an elaborate set up to check on your herp.
Hope some of that is useful

I agree with Kel, repticarpet is OK, but not the best.
I started off with repticarpet originally and within 2 or 3 days switched. The geckos get their teeth and nails caught in it constantly, especially as it starts to wear and tear and the stitching isn't as tight as it was when you buy it.
The slate or vinyl tiling is wayyyy better. I was reluctant to buy it, but its great! Its easier to clean, holds the heat better, and was way cheaper. In my 20 gallon tank, I only needed 2 tiles. And it left space for a paper towel toilet area.

Edit: Barks and chips and sand are also not a good idea. When the gecko goes to eat, it could end up getting a mouthful, which can cause impaction.

Repticarpet is a step up from loose substrates, but if you want to spend some money on more permanent substrate look at tile from Lowes.

Agree with Kermit

Though they cannot become impacted from it because it isn't a lose substrate. Some reptiles just don't do good on it. Leos and bearded dragons tend to get their claws stuck. And get in a panic, either breaking the toe or ripping the nail out. And it needs cleaning on a regular basic so it doesn't hold nasty bacteria.
