i've been looking to figure out which salt to use in my tank i'll be setting up, just trying to get the last few things together b4 jumping in with both feet, i've read up on IO reef crystals, and red sea coral pro, mostly because they come in the biggest amounts, are these ok, or is there something better, i'll be ordering them offline, so i will find the best price, just wanted to know what others are using with success. thanks all
