Dino i.d pls picture attatched

I think it's the sand dwelling species. I already started dosing silicate by brightwell. Instructions say to start at 1 drop per 20 gal a day for 2 weeks. For battling dinos what should I up that dosage to?

Also I read that the salifert test kits for this are not accurate enough. Should I bother testing with something else?
