Good article which most of it was gleaned from some scientific articles that have been around over the years.
An important point brought up in the article is that when Acros feed they send out those digestive filaments to absorb their food. They are actively trying to eat......polyp extension on the other hand, doesn't mean feeding, it's more of a response......smililar to a dog salivating, but without the saliva..........with saliva for a coral means messiral filaments present and active feeding like below.
I would have liked to have a video of this coral as the filaments were way more heavy and easy to see.......and by the way, this was from the juices and feeding PE mysis to my fish, which also likely carries all the essential amino acids in those shrimp and juices.
From my experiences, when it comes to Acros, unless your corals are pastel or pale, dosing commercial products is not needed and it isn't going to increase color or growth. You'll get more out of getting the correct form of lighting with respect to sepctrum and par. if your running a fully populated reef with fish and corals it's possible to have the opposite effect and brown out corals.
Now, when it comes to zoas and goniopora, non-photo corals, I'm more intrigued that they have value.
As far as LPS......just look at their mouths............do you really think they want or need to take up amino acids when you can feed them meaty food directly that have all the aminos in them. A big mouth or body design like that isn't made to suck aminos out of the water column. They create a lot a surface area to catch plenty of light and have big mouths to capture large food pieces.
! cant wait to get this acro power started.
