I have a 75 with no sump. A hob reef octopus skimmer. I came up with a bad case of dinos.
Here is what worked for me.
I purchased a bottle of Remediation by Aquavitro from my lrs. It’s a combination of bacteria similar to what’s used in treatment plants.
I did a two day lights off, but ambient room light okay.
I added a uv sterilizer and now my sand and rocks are clean.
My parameters have always been stable at
Nitrate 10-15
Phosphate0.08
Salinity 1.026
Temp 78.
I run a nutrient rich tank and still got dinos.
Interestingly, according to several reliable sources,
Dinos, diatoms and Cyano are the three most common and important organisms in ocean reefs. Just not in ourctanks.
My corals and fish are thriving.
I’m more and more convinced that it’s not the nutrient level but the available physical space for a bloom. Something changes, perhaps something we do not measure, a physical space on the sand/rock opens up and one of out three hated guests start to thrive.
I’m sure that I’m not the first to connect these dots, but just my two cents worth.
