Dino's are a protazoa(Sic??) with a flagellate (tail like structure) that they propel themselves with. They contain neurotoxins and they thrive on nutrient rich water and light (most contain zooxanthellae). They do not consume silicates like diatom algae nor do they use irons etc.
I'd consider cutting my photoperiod and removing as much organic material from the aquarium as possible for as long as you can stand. Don't just do a water change but clean under all your rock, clean/rinse out your rock etc. Rinse your gravel/sand etc and see how that goes.
I'm only repeating what I've read in the last couple of days, I really haven't got a clue was just curious and wanted to see what information was out there.
