Fish death after reef roids

[jts813]

I used reef roids for the first time yesterday. Target fed for my 29 g tank. 3 of my 5 fish died within a 6 hour window. Inverts all fine. I used the instructed amount. I actually split the dosing to a 10 gallon nano as well. The 10 gallon nano has 2 clown fish that are ok. The 29 gallon inhabits I’ve had for a bit. Everyone accounted for earlier in the day with normal behavior prior to reef roids. What happened? Some kid of oxygen event? Or toxin that affected the fish? I ran carbon and did water change. May never know but wondering if this is something that has happened to others using reef roids but don’t really see any similar accounts.

Ive not had any issues from using it. How much did you dose? And how did you mix it, was it thin or thick ? If it was thick, Is it possible the fish ate it? Even if they had, I am not sure that would have killed your fish.

Could of been oxygen depletion! When reef roids are added, bacteria can bloom rapidly and consume oxygen.

Personally I'm skeptical.

My fish eat it all the time.I've never had any issues.And I don't follow the instructions at all.

Agreed. If it was the roids I would expect the same result in both tanks. I never even measure it. I just scoop some out and dump it in a little tank water shake and pour in the tank.

Did nitrates or Phosphates jump way up?? Roids capable of doing this often though at lower level and if under filtered may play a role
Did the fish die with their mouths open?

Thanks for feedback. No ammonia or nitrate spike. Didn’t check phos though. Agree that doesn’t seem typical for reef roids to cause fish death. Maybe a bad batch? Odd that inverts fine. But maybe that points to some oxygen event then chemical or nutrient? It was a goby, tail spot blenny, molly that died. Chromis and firefish are doing well.

My son used it liberally when we first started . We had no fish deaths but it did cause Hair algae to grow and tried to take over the tank . Took me six months to get rid of it ( no chemicals )
