Hello. I been battling Dino for about a month. I got it way under control thank god but there's still one rock that it just keeps coming back. I'm running Carbon in a filter bag and a gfo reactor. How do I get rid of it for good?
 
My friend battled for 6 months. Then a lfs owner told him cut light hours to 4 hours a day a slowly bring up by 1/2 hour a week back to normal. While doing the other stuff. Remove with turkey Baster and nutrient export. Problem stayed away. Good luck
 
Dinoflagellates are a real pain. I have been trying to keep mine under control with some success (I have tried Dino X, Hydrogen Peroxide, lights out but my SPS always suffer with that).

At the end of the photo period I cover all the sides of my 150gl tank, I will not allow any light from TVs lamps, etc enter the tank.

I only dose organics and trace elements (also do water changes) after lights out as they seem to fuel the growth of dinoflagellates. (I used to do the same with carbon dosing but PH would drop further during night and my PH is already on the low side at night.

Once a week I stop all the pumps and flow in the display tank, few minutes later the dinos start floating, coming out of pumps/rocks, etc. That´s when I dose a flocculant, turn all the pumps and let the skimmer get rid of some.

A month later and I only have some that love to settle on my two gyre pumps. I don't understand why but my gyre pumps are like magnets attracting the dinoflagellates.
 
We had them for over a year. Killed everything in tank and we are just recovering this last year. All fish died except one. We moved anything living into another tank to try to keep corals alive. Think we beat it by doing all remedies combined. I wrapped my tank in many comforters so it was total blackout and dosed hydrogen peroxide as well as raised my ph with kalk to 8.2 or 8.3. Read somewhere that the higher the ph the better. Took about two weeks and it stayed gone. Water changes really make them go crazy though so even after they were gone we didn't change water for awhile. Not sure if you could move corals to a smaller frag tank or something so they don't die with a few weeks of no light but we have not had any issues since.
 
Hello everyone, I'm new to the site but have been coming here for a while for the additional info. I had a 125 reef infested with dinos. growing on the glass, rocks, corals you name it. After about a year of this getting worse and worse I finally removed the sand as had been suggested but it was still growing, I finally blacked out the tank and dosed 150 ml of 3% peroxide for three days. The tank is gorgeous now and I only suffered the loss of my cleaner shrimp and arrow crab as expected from articles I've read before. My soft corals did fine as well as my hammer and torch. Coraline showed no effects either and the water is pristine. I have since added new sand 3 days ago and i included some pics of the results. Good luck to anyone battling the the demon dinos.
