Ich or velvet?

[Jake_the_reefer]

Very hard if you have coral or photosynthetic inverts. Needs to be fallow and dark. After 2 tries I tossed like 2k in frags/ corals, coppered fish in tubs , put NPS inverts in large bucket with filter. I drained tank, filled and ran 3 days with fresh water, emptied refilled with saltwater, bacteria and recycled.

I've never heard of lights out as the parasites feed on fish not light. And yeah the tank has a decent amount of acropora and lps

The velvet parasite cycles in less than a day. Light has nothing to do with it other than it used to be thought that parasites are most active when fish are sleeping so they have an easy target for reinfection. That seems to not be true either. Spend more time researching the scientific literature and less time listening to forum anecdotes. If you can swing it:

Thank you! I will start a fallow period as soon as I can. Hopefully my normal 2x a week reef roids and aminos will be enough to keep the tank going. I'll of course monitor phos and nitrates

Dinoflaggelate organism Amyloodinium ocellatum is know to survive photosynthetically , look it up. Also will live and be carried by inverts. Ich is a blessing, easy to control.

 

[h2so4hurts]

The maximum lifecycle of Amyloodinium ocellatum is 30 days. If it doesn't find a host within about 8hrs as a trophont, it dies. I'm not sure what else to tell you. This is what the literature says. It has been seen to infect clams, flat works and shrimp but "inverts" is a stretch.

Your correct trophont can't live off of host, however before released encysted have been shown to remain dormant in substrate for up to six months. Btw clams, flat worms and shrimp are invertebrates.

Update. The wrasse went from looking okay, to being completely white to dead within 24 hours. The last fish alive is a yellow watchman goby with 0 signs of infection which I still give credit to my cleaner shrimp for this.

All being said the tank is now severely understocked with only a 1.5 inch goby should i increase my reef roids and amino dosing from 2x a week to a higher frequency to keep the water full of nutrients?
