I have a Powder Blue, Blonde Naso, Achilles, Sohal, White-tailed Bristle Tooth, Tomini, Chocolate, and Twin Spot Tangs and none of them were effected. It only effected Tangs in the genus Zebrasoma. I also have multiple wrasses, Single Spot and Magnificent Fox Faces, a pair of Masked Angelfish, and multiple gobies, but none of them were effected. None of my Cleaner, Fire, or Peppermint Shrimp or Coco Worms were effected either. They are all in a 400 gallon mixed reef with perfect parameters. I check my nitrates, nitrites, phosphate, and KH at least 3, if not 4-5 times a week and send off a water sample to Triton for ICP once a month. I am not chasing numbers, just making sure things are stable. I have well calibrated pH, ORP, dissolved oxygen, and salinity probes and none of them showed anything wrong. My 200 gallon sump has separate ROX and GFO reactors and has an 80 gallon refugium with a rotating ball of Chaeto(the reason I decided to play around and dose some iron) 20" in diameter under two Kessil H380s that make it dense and dark green. I do 100 gallon water changes 1-2 times a month with water from an eight stage RODI and HW MarineMix Reefer pharmacy grade salt. My tank has five WAVs and two XF250 Gyres that pump 35-50 times turn over that is randomized through programming and storms every day for an hour a 75 times to keep detritus from building up anywhere. Every one of the fifty different species of SPS and LPS are flourishing. Everyone of the fish is FAT and happy because of five feedings a day. They are fed with a mix of five different pellets on an auto feeder and a soup of frozen mysis, Rod's Original, Phytoplanton, Oyster Feast, Calaneeze, Selcon, Reef Roids, and Reef Chili.
Nothing showed any sign of issues before the dose and only the Zebrasoma perished. It had to be Ferrion. There is no other explanation. I wish Brightwell Aquatics would seriously look into it before this happens again to anybody else.
I have seen multiple threads on this issue and I wish all the companies making iron supplements would put warnings on their labels like so many other products do when they interact poorly/lethally with certain species of fish. This is an avoidable outcome if the necessary information is available to everyone as they look into these products.
Regardless, the rest of my reef will move on past this and so will I because I love everything about this hobby! My tank is certainly half full, not the contrary. Happy reefing!!
. Hope they will be fine
