This is my first post here ever so be gentle with a humble viking which has another native tongue hence excuse me if my English is poor...
I have been a passive reader of this forum for a loooong time and I still learn a lot from it so thank you all!
I have been in the hobby since 1986 and believe it or not I have never had a fatal outbreak of any disease of any kind, in the early days over here we where happy if the fish survived more than 6 months anyway cause of all the bad methods which they used during collection like cyanide etc. Plus of course very limited choices in regards to equipment etc, I remember my first skimmer was 210cm tall with a wooden airstone in the bottom of it and that was at the time the best news to the hobby we could dream of but still not very good he he.
Anyway to the point, I have had a massive outbreak of some kind of disease which I have not been able to identify properly even with help from Norwegian salmon veterinarians but there are theories. We think it is a cocktail of parasites which have entered the tank in a mysterious way. I have had signs of itch(irritans), oodium( is that the right term?) and even black spots and bloated bellies maybe also brooklynella if that's what it's called. As of right now I have lost almost everything in the tank, and the tank I am talking about is a Red Sea S-Line 500:-/ All which is left is a file fish, two yellow tangs, one six line wrasse, one Dorry and three Blue chromis so it is fair to say I am devastated but still determined to save the rest of my loved ones
This is what I have done today: Bought myself a Red Sea Max 130D to use as a hospital tank cause my 40l quarantine tank is way to small for the fish which is left. After that I plan to tear the whole thing down and start it up again. Does this sound ok? I don't want to leave it for like 3 months with water in it to make sure all parasites are gone. So I thought just emptying the whole thing is the best way to go, I have had friends over here who have had the tank going with no more than water and rock after an outbreak for as long as 6 months just to experience a new outbreak 3 weeks after re-introduction of the fish. And I don't want that. Do you guys agree on my thoughts regarding this? If you do what would you use as a cleaning agent after the whole tank is empty to make sure there is none of the parasite buggers left.
Sorry for the long post but this is something I would appreciate some feedback on as disease is something I have been spared for in the past and because of that limited experience is my culprit, but I guess there is a first time for everything.
On the forehand thanks for any input.
