I received a sample size of this product(thanks @bart84 ) and figured it can’t hurt to try, well WOW!!!! It does what it states. Within seconds I could see feeding response in almost all of my lps. Polyps extending like crazy right befor my eyes. I had my lights on and it looked as it usually does while my lights are off and I’m night feeding. With this stuff you could feed anytime you felt like and the coral would be ready to gobble up what ever it is you are feeding such as reef roids and reef chilli like I do. Anyhow nothing happens unless it’s got a pic so here is one from my chalice. Typically it got furry every night since I got it like 2 month ago. Little 1/8” tentacles all over. Fed a little polyp booster and BAM we got some serious reach!!!!
