I think if you have a bacterial bloom I would stop, start the skimmer back up and do a water change and maybe add a uv sterlizer. But this is my personal opinion and I'm not expert in that I will let someone else chime in for some help. Also retest the samples from the sand and from rock to re identify here you may have more than one type or maybe the stuff on the rocks is just cyano. I would reccomend get microscope pics of the dinos from sand and rock and a full tank shot post it here. This will help us get started. In helping you move in the right direction.Rocks and sand bed.
Seems I’m having a bacteria bloom. White cloud.
Should I stop this recommended method? Or see it through?
