The only reason I switched in the 1st place was i need more than what came in the small pack and havent seen any difference in freshnes. I dont have the time to stop every week to buy a bag and got tired of only being able to get 1-2 bags at a time locally, so I switched. all of my fish tear it up, wrasses, clowns, tangs, even my randals goby will swim up and get some. Not dissing any LFS you guys all know me and I buy from all of you, including you and the Tulsa group, besides if the couple bucks difference put someone out of business then they werent running their business right to begin with IMO. I still buy my coral, phyto, food and fish through LFS and ocasionally someone tearing down a tank. Just giving an option. I do occasionally buy the red "from an LFS" and mix it in though. Figure they would like a change once and awhile.
