R0/DI water

I have a 34 gal red sea tank and thought about taking something out of their however I had ick in that tank and do not want to risk bringing anything in to my new tank.

 

I have read, and this may or may not be true that saltwater ich (Cryptocaryon) is a protozoan that is present in all saltwater & marine aquariums and that it usually doesn't bother fish unless they are stressed and their immune system is lowered. There seems to be some debate on this just like anything else but it didn't stop me from adding substrate from my once ich having tank to the new one.

By the way in my reef tank, of 6 fish, one day one fish got ich (after a near death injury) and none of the other fish got it, not to mention I hadn't added any new fish in about 6 mos. prior to this. I talked to one person once who said he hadn't added a new fish in 3yrs, no corals or anything else in over a year, and one day a fish came down with ich out of no where...

I'll stick to the idea that Cryptocaryon is just there...

 

Don't put in any chemicals just let Mother Nature do her job. Slow down my friend.

 

I'm all about slow.. I'll go the chromis route.. I already have two of them from cycling my first tank. Otty, Do you think I should use one or both of the cromis for the 120?

 

I don't think you should use a damsel for a couple reasons. 1. Even though damsels can survive cycling, it is extremely stressful and not really fair to the fish. Also, there are other ways to get it done like with live rock or shrimp. 2. Once you are done cycling, the damsel will be extremely territorial and very difficult to remove. Having an established damsel before anything else will greatly limit your fish options.

 

I agree with LCP136, although I didn't cycle with one, I bought one because it was cheap and pretty once. Well, needless to say we were happy to find it dead one morning.
