Update.....Well after the sailfin looking ok again , I reduced the SG
further as still too high and he broke out in major cysts and tonight was hyperventilating. I checked the SG
again and it was 1.011. Still work to do on that. Nitrates a bit high but nitrites out the window so applied emergency meds to eliminate the toxicity of any nitrates, nitrites, ammonia and chlorine. 2hrs later and he is dead. Don't know if it was the nitrites or meds. Am turned right off the hobby at this moment. But at least my mandarins have come good again in the DT and my clarki is full of life after I reduced the SG
in that tank within a healthy range. Lost my anthea, a dartfish, dotty back,banner and bi colour goby in the process. Not buying any more fish for that tank or trying hyposalinity again. If I finish setting up my 250litre, I will be QT everything first!
