I am unfamiliar with that product, but I do know that SeaChem makes quality products. It shouldn't be an issue about finding it where you live. If you are buying from a pet store, you are getting ripped off and you are supporting the trade of live animals with people who don't take care of them. Go to aqaticeco.com or thatpetplace.com and order it from there, internet is the only way to go with herp supplies!
