As the title states, Phosphate RX killed my fat and healthy 2 year old yellow tang. I have been going through a fluconazale treatment and noticed a rise in my phosphates from unreadable to .079 (per my Hanna Check). The treatment says 6 drops per 10 gallons will reduce phosphates by .5. So I did .5 / .079 and figured I'd need about 1/6 (at the most) of the dosage to drop my phosphates.
I went with 1/8 of the dosage and dripped the phosphate RX into my filter socks. Tank was cloudy which is suppose to be normal...I then went and checked on the tank about a half hour or so later and my fat and previously happy yellow tang was on the bottom, leaned up against the glass breathing hard...I scooped him out and threw him into a hospital tank...2-3 hours later he was dead. Bummed because I got him when he was a little guy or girl and he / she was pretty much a model citizen of my tank...I never saw him acting aggressively towards any fish. Mostly minded his own business and grazed on the algae clip all day.
I did some more research and found that a number of people have reported having issues with the Zebrasoma species and Phosphate RX. I'm not sure why this is unique to them, but it seems that I'm not an isolated incident of this outcome when using Phosphate RX. All of my other fish, coral, inverts etc had no problems with the treatment...
If you're going to use this stuff and have Zebrasoma specieis of tangs, BE CAREFUL!
