Well, came home to a very unhappy tank. Had to do an emergency 15 gallon water change and I’m thinking of repeating tomorrow. I think it may partially be my toadstool leather releasing terpenes for some unknown reason b/c after putting the ‘stool in the nano (intended to do this for a while) I saw corals perk up a little. As it was lost two of my new Acros and my big green monti was spewing mesenteral filaments. The lps that was totally unfazed interestingly were the bowers and micromussa in particular.
