I have dealt with dino’s On several different occasions. This is what I recently did that destroyed them.
1. Use freezer tube and manually remove as much as possible. Alternatively and this works very well, run rubber tubing from display tank down into your protein skimmer intake. I then added ozone via the Venturi at a rate of a 100mg/hr. Use the tubing that’s in the display tank and hooked to the protein skimmers intake to suck the Dino’s down into the skimmer where they appear to be destroyed upon contact with the ozonated water.
2. Black out tank for 72hrs. When I blackout a tank, I mean completely black out with black aquarium backgrounds, black sheets or cardboard.
3. Run carbon throughout this process.
4. I ran ozone at 35mg/hr during the treatment and have continued to run it after the treatment.
5. I also added an air stone to the display for additional oxygenation.
No more Dino’s! I attribute most of my success to the use of ozone. My tank is crystal clear. The corals are happy! I’m happy! No need to tear the tank down! The Dino’s I was dealing with were the kind that obliterate snails. I’ve tried every other approach out there but this way worked for me and frankly wasn’t terribly difficult at all.
