Aquarium safe?

CatSoup

I wanted to use some peat in my magnum canister instead of carbon. Are any of these safe to use?

Only 100% natural peat with no additives will be safe to add so you will have to go to the store and scrutinize each bag to make sure the one you are getting is pure peat. So you can pretty much count all the miracle grow stuff out, start with the cheapest bag, usually the the cheapest one is most pure since its from ground to bag instead of other steps that add other things to the mix.
