Looking for some guidance

That is probably dinoflagellates, but sometimes there is a brownish cyanobacteria. Dinos can be pretty persistent.

Btw, your Dracula Goby is a Hi-Fin Goby.

Do you have any clean up crew?

Yes i have a cuc, turbo, astrea, nassarius and margarita snails and various crabs. Total of 15 crabs and 20 snails.

Anyone know where i could buy Metronidazole Powder in Canada?

I came across this thread on Dino:

My plan is to try h202 first, if no success hopefully Metronidazole will work. I know seachem makes metroplex but if i can get a generic Metronidazole that will suffice.

I think maybe your waterchanges aren't very effective. Could you describe how you do a waterchange? What steps do you follow? Do you use RO/DI water or tap water? If RO/DI, have you checked the TDS of the product water?

Even though Metro is generally considered reef-safe(ish?), it's not something I would be adding to my reef.

I use spectra RO/DI, just replaced all the filters a couple months ago, i have a TDS meter and output reading is 0. Based on the thread from reefcentral some say not to do any water changes as the Dino thrives. At this point i don't have very much coral left so if using Metro only affects coral in the short term i'm fine with that. I made a decision not to purchase any coral since this started 6-7 months ago until i have the bacteria all cleared.

The steps for the water change is filling a 30 gallon tub and mixing the day of. I have used various types of salt, once mixed i transfer over to the tank on the same day. I checked the PO4(hanna) in the mixing tub and was registered at 0, i supposed i could try a different tub if the concern is leeching.

Yeah, but there's a reason it came to be. I'm more curious about the waterchange itself - do you simply remove old water and replace with new water or do you get in there and turkey baste the rocks and vacuum the sand?

Do you have a microscope by chance? It's easy to tell dinos from cyano under microscope.
