Large amphidium dinos?

[Notsolostfish]

I just Id my dinos that they are large amphidium dimos? They are just on sand, really ugly but they dont do much than that. What are some ways i can combat this type of dinos? I have a dedicated UV 57w to my 200G but it doesn’t do much.

There are a number of threads on what folks are doing for this type.
Like you said, it mostly just looks ugly, so is not a reason to go really aggressive on any treatment.
