Well, some of you have experienced the pink lemonade I had for years. Its dead- completely white in a matter of a couple weeks. My nitrates have been around 10, so I decided to add a biopellet reactor. Now I have a strawberry shortcake dying quickly (see picture). My nitrates haven't changed. What do you think? I also have a tri-color that looks stressed, turning white from the base. On the shortcake and lemonade the zooxanthellae died quickly and coral turned bright white.
Can other corals kill each other? The lemonade is being touched by another shortcake and the strawberry is being touched by green slimmer. Both in the area that turned white first.
pH 7.9 recently dropped to 7.6
