Petco just announced that they will be shutting down the Dr. Foster and Smith website. Petco bought out DFS not that long ago, and have now decided to close the doors to their facility, and lay-off 279 employees. This won’t effect live aquaria, but DFS will be gone in the next 120 days. Maybe this is why Petco had that huge sale on Tropic marin salt? Maybe they are getting a jumpstart on clearing out the DFS facility.
