Recently I posted a thread about my long running battle against Dinos. I noted the repeated unsuccessful attempts in this thread
https://www.reef2reef.com/threads/a...ion-rate-out-of-control.1143882/post-14264599
Well, yesterday while observing my tank I realized the Dinos had disappeared. I cannot believe it, and I have no idea why.
As recently as less than a week ago they were spreading like wildfire. This picture was taken on 3/29/2026 from a tiny sample of a flowing string of reddish-brown snot, which has now disappeared.
.
As described in my attached thread, over a period of time I tried every solution suggested in the various threads on this topic with no lasting success.
About two weeks ago I made only one change to the system which I guess must have led to this success. I reduced the duration and intensity and color spectrums of the tank's lighting.
I have not taken par readings since the changes but will do so and report back. I will say, the reductions I made, while material, were not so great that the attractiveness of the tank was noticeably diminished.
Previously I had set my lighting levels high to support SPS coral. During the Dino epidemic. most of my coral was killed. As the die off occurred, I moved what surviving coral I could to a 20-gallon quarantine tank where it has survived. The only coral still in the 120 gallon infected tank are several zoa colonies and a couple of mushrooms.
If the dinos don't reappear, I will hold my breath and slowly move some of the quarantined coral back into the tank.
