I posted this in a different thread but perhaps it is more relevant here. I have a relatively mild outbreak, but they are persistent. I have tried or am doing; bacterial dosing, reduced photoperiod, vibrant (1 month), peroxide (6 weeks), manual removal via filter floss.
It is hard to say, but the only things that I can truly say have helped are lights out and manual removal. If the other methods have, it has been subtle for me.
I may try dosing phyto and pods, hoping to further crowd out the dino and grow some other algae.
I have not tried dino-x or removing the sandbed. I guess those will be next on the list.
