tank in fallow next to non-infected system

Long story short, I have ich in my DT.
Not a very bad case, everyone is still eating.
Cleaning and re-establishing my hospital tank now. I plan to use cupramine as I have multiple fish infected. (I assume all fish are infected; only have 2 though)

I have a spare tank to set up after the 2-4 weeks of cupramine so the fish aren't all cramped for the following 8+ weeks of fallow.

I'm concerned about having this tank in close proximity to my DT in fallow, around 1' away.

Is this a valid concern?

Probably not. I think the odds of transmission via aerosol are pretty remote.

However, do be paranoid about cross contamination via wet hands, splashing water, feeding apparatus, etc.

This. No sharing of equipment.

excellent advice. thank you.

Now if there was only a forum for convincing your significant other you need another tank in a place they may not agree with.

There is. In my case, it is the ladies shoe store. For others it may be something similar.

Actually odds of aerosol transmission are quite high. I've seen studies on it, and I've also seen it for myself

I did not know that. Got a reference link Bill?

I'll try and do some digging. Might have to wait till I'm back at work where my primary reference source is (Noga).

The best case (example wise) I was involved with was an Amyloodinium outbreak. Professor I was working for decided to ignore my advice on QT'ing wild caught fish in another room, and brought them into the main lab. The outbreak in the lab reared stock occurred in a perfect semi circle (wall was on the other side ) around the wild caught stock, leap frogging over the tanks immediately next the wild caught stock. Perfectly matching the arc of spray from the breaking bubbles of the airstones, and infecting 2 separate but adjacent systems.

VERY interesting. Aerosolization would explain why I've had such a hard time eliminating the parasite, since my QT was in the same room as the DT (in fact, the QT was only about a meter away). I've since moved the QT to a completely separate room in the house.

Would using a powerhead/HOB filter alleviate this concern? Airstones do give off a mist once the bubbles break the surface.

It will certainly reduce it, though not entirely eliminate it. Covers will also help reduce it. Absolute best of course is a separate room.

Thanks. If you get a paper reference, I can try to google it. The contamination process makes sense but I had no idea it was possible.

Got it: "Infective dinospores could be transported in aerosolized water droplets (Roberts-Thompson et al 2006). Droplets from static systems were shown to be transmissible for up to 1.44 feet however droplets from dynamic ones were shown to be transmissible up to 9.8 feet. This means that adjacent aquaria, and potentially ponds, could spread the infection. [edited] This means that aquaria if situated close together should be covered." These references were originally from Fish Disease: Diagnosis and Treatment By Edward J. Noga but after additional use of Google Scholar, there were others. However, all were focused on amyloodinium.

I should have researched further before answering.

I've seen many posts where folks talk about having to QT in close proximity to their DT due to space limitations. Especially following an "emergency" ich/velvet outbreak. The information contained in this thread may explain some of the fallow failures we've seen in this forum. The information contained in this thread probably needs to be made (or incorporated into) a sticky.

If Bill wishes me to do so, I can figure out where to update existing stickies.

I think he's referring to the reaction of everyone learning about this

It's certainly the reaction from the professor I mentioned
(he never second guessed me after that )

Thanks for the excellent suggestion. Steve was pretty quick on the writing, so it's already done

I can totally understand. General reaction and specifically in the case of the professor.
