any coraline growth? don't see ANY in your pics... something may be outta whack, did u try to seed any?
our wavy lps hate low no3 and po4, we dose both. i recall in coral collecting videos that a lot of these torches/hammers are collected near rivermouths (lol). therefore 'higher' nutrients. anyhow, if TSA ever said anything to me, i'd certainly listen, lols. and what's the typical dKH of the ocean?
manganese makes ours happy, they tend to extend more... but then you need to icp the water on a regular basis.
medication will only address symptoms.
