Had to take the leap. Everything was going great, then out of the blue, there is a lot of recession. Water is all good, it didn't make any sense. Broke out the flashlight at 3 am, and amphipods are mobbing every coral exactly in the areas of recession. Acans, favias, lobos, the base of newly fragged SPS, even the Dendro. Interceptor the tank, and one week later, everything that had receded is growing back. Everything that was doing good is doing even better. The Tyree Red Watermelon chalice popped out a ring of new mouths. It's like a night and day difference.
