I use the amino acid one...for me it works, its a good coral dip. In the ocean amino acids are like unlimited, in a captive tank the only way is to dose...Im not sure about the other 2 but the amino acid one is good
I use the brightwell version of amino... just think about it from a human standpoint... what do vitamins, amino acids, etc do for us?
But I say definitely use the amino... I add it to the food I use to TF the coral... it's also supposed to help with recovery after being stressed by being added to a new system... my corals seem happy. then again..I dose a ton of things
here's my regime:
calcium reactor
the rest are all brightwell products which to me i've had the best success with.
vitamin c (twice a week)
garlic drops (twice a week w/ food for fish & coral)
magnesion
plankton (once a week added to coral food)
Coral Amino (twice a week w/ food for coral)
Koral Color (twice a week w/ food for coral)
Koralle VM (twice a week w/ food for coral)
& the only thing not brightwell that I dose is
Reef Solution...probably THE BEST SH** that I've ever dosed into my tank... I saw the difference within a week.
