I have a tank lying around that I want to start a journal for. This will be a SPS dominant tank with a minimalist approach. I'm going to bare bottom and going to have a wrasse in there to take care of any pests that I might come across (even after Bayer dipping and Seachem Reef Dip, some still inevitably make it through). Question: Is pyrex safe for reef tanks? I'm going to put sand in it for the wrasses.
