I had tried everything to rid my tank of Dinoflagellates, even obscure methods such as yeast dosing.
It always seemed like I was on the cusp of ridding my tank of dino, but whatever I tried never quite worked.
I had learnt that dino have the potential to take up carbon dioxide and use it, even in the absence of light (such as a total blackout). I realised that the reason I may still have dino was due to a potential oxygen deficiency.
I used Dino X and the Oxydator in my saltwater tank and I watched the dino dying away on a daily basis (alongside the cyanobacteria).
I am certain that I would still have dinoflagellates if it had not been for the Oxydator.
