YES,,afte I got home,,checked the bag which still has enough to do another smaller tank, and it is indeed the organic choice potting mix in orange colored bag.
Sorry for the mis-information.
Was green bag I bought at first but decided not to use it after other's more expierienced with the product warned otherwise.
Can vouch for the potting mix by miracle grow which is what I used in two tank's.
