First off, the Salifert test is free form Ammonia I believe, in which you should strive for less than .5, This equals out to be about .02 in NH4(ammonium) which is about the max you can go before damage is likely to the inhabitants, so you are right on the border line Vegasdude, again too ph also plays a factor in this(in which lower ph will be to your advantage). A tip for you though, I think hospital tanks are a waste of time and only add more potential stress to a fish who is moved from his "normal" tank, to another "new" environment. I have never had any outbreak of disease in my tank, which I think may because of NSW(natural strength sea water 1.025-1.027)which aids the fish in fighting disease, and also have a pair of cleaner shrimp, which I now feel play a huge role in your tanks health too, its like having a lil doctor on permanent call, and they do work very well, IMO rather spend $20 on a cleaner shrimp than countless dollars on chemicals, the only chemical i have bought is basically Lugol's solution and have only used it once to dip an already plagued hammer coral. I think though that when you move fish from tank to tank the whole treatment/hospital tank idea is detrimental from its own merits. I have never had one, nor will I ever in the future, I think the best medication for fish is, good water conditions, stress free environment and its own immunity capability.
