Brightwell Aquatics Koral Recover - Coral Remedy for Treatment of Live Corals & Regrowth of Damaged Coral Tissue, 500ml, 500-ML (KRC500)

I mistakenly purchased this thinking it was just to dip a few stubborn frags in to kick start the a bit. Well when it came in and I noticed it's to treat the whole tank, I set it aside and was just going to keep it as I try to never add anything to my main display I less I have to.Well, the very next day, my Acropora had retracted polyps as they're normally extended. Then came the zooxanthellae expelling through the tips and polyps.I'm pretty sure it's Acrobacter, Vibrio, or a few other bacteria that came come from other corals or through frozen food even.I dosed the Brightwell Koral Recover and didn't notice anything immediately. The second day the RTN was visibly slowing down. Today is the 3rd day and it's fairly stable. I just received my bottle of Ciprofloxacin and I'm going to treat with Cipro and stop the Brightwell for now.Does this work? YES! It does and if you have corals with RTN, STN, or Brown Jelly, pick this up and have it on hand. A mistake that I made ordering probably saved countless colonies of Acropora.

heavy witch hazel smell that permeates for long periods thereafter, but rapid tissue necrosis stopped before frag was entirely consumed, so if this stopped the loss, smell was worth it!

Didn’t help my tank. But then again, half of products out there are just snake oil

Decided to frag my Space invader pectinia coral which has grown to the size of 1.5 softballs. Being a novice, I do not know if I cut at the 100% best places. My go to fish store recommended this to dose in the main tank to help the mother colony and frags recover and not lose flesh and after reading the directions, the frags and mother colony recovered splendidly. This treatment also saved my gold torch that was also on the decline too due to a tank swing when on a 10 day vacation and power outage screwed up the dosing equipment.My recommendation is to make sure to read the directions very carefully and turn off any equipment that it recommends to do so.

Don't want to have to do a 30% water change on a 200 gallon aquarium after using. Must not be good ingredients if you have to replace so much water to get rid of it

Although I feel like this product works fine I don’t have a protein skimmer. so I wasn’t actually supposed to use it. It did help my corals, though I just had to do a bunch of water changes to offset.

Was a bit skeptical with how this product is described, but it always seems to help whenever I use it. I noticed its effects most in my zoanthids. They were closing up and after using this product, they began to open up again. I use it every now and again to treat my tank if I see unhappy corals.

Arrived with the contents spilled in the box. Disappointed
