I had dinos about 1 1/2 year ago. No clue how they came about, just that it is a nightmare. Battled if for a good 4 months trying everything. Black out on several occasions, H2o2 dosing, mag, ph, water changes, no water changes, lost corals from the dosing or the dinos. Nearly took it all down and on a whim took out a UV sterilizer I had bought years ago and never used. Put the UV on for about 3 weeks and never saw the dinos again
I guess there are many, many types of dinos and not all respond to the same treatment
