First off I went there to buy instant ocean salt. The lady had that and 2 other brands that I've never heard of. IO cost $19, she recomended marine environment which cost $21. She said that it decholrinates tap water and it has essintial supplements for reefs. Well I bought the marine environment salt and now I realize that I should of went with the IO. I dont even know how much salt to mix, the instructions don't say anything. Another thing is the receipt says " NO WARRANTY ON LIVE STOCK!!! WE MAKE EVERY EFFORT TO INSURE THEY ARE HEALTHY BEFORE WE SELL THEM" First off I say dead coral, dead inverts, and some fish look like they have crap growing on them. Very healthy huh!
