I posted on a thread on Facebook saying that Liveaquaria salt is Fritz salt. No one from Fritz denied it, they just asked me where I heard that in a pm back to me. I posted back saying it's pretty obvious from the stats and packaging. They didn't say anything back. It would have been real easy for them to say no it's not, but they didn't.
Bottom line is there isn't that many facilities making aquarium salt in the US. Liveaquaria has shown no such facilites. The wording is almost identical, the parameters and quantities are the same, and no one from either company had denied it. I'd say it's safe to assume it's the same salt.
It's a pretty decent salt. I've been using Fritz for almost 2 years and now am using Liveaquaria. I was able to get 205 gallon boxes of liveaquaria from drsfostersmith for $28. Hard to go wrong at that price! Unless everything dies of course. Lol
