I usually perform my water changes from a lfs using Tropic Marin. On occasion, I breakdown for the sake of convenience, and buy from another lfs that uses Instant Ocean.
Last time I do that! The IO just stunts my corals and brings my kH down to 10/11. When I use Tropic Marin, my corals perk right up and my kH stays at 13. I think there's a big difference. Any other experiences?
