I broke down my old biocube after it was overwhelmed with dinoflagellates. I killed everything and sterilized the tank. I then started a new system of 75 gallons that was running smooth for a few months until i noticed a familiar sight. Dinos! ugh! Due to the chaeto, live rock, and efficient skimmer the dinos are not covering the entire tank, only the bottom and back glass. Any successful eradication methods out there? So far the livestock is unaffected.
