Hi, I'm not sure exactly what I really need for my QT, is it just a filter, powerhead, and heater is enough. and one other question, do I really need to put my new fish in the QT and for how long ? I haven't done that way, so everytime I get new fish, I acclimate them and just put in the DT but then after a few days each and every one of the fish died . I test the water parameters and they all read fine with nitrate-0, nitrite-0, ammonia-0, ph-8.3 and SG 1.024 , so I thought okay the water looks good so nothing should happen but the fish still died one by one. I had between 4-5, I think it's too much but my stubborn husband won't believe me so now all the fish had died, now I only have a sailfin tang in a 55 gal tank. after all the other fish died, I thought the sailfin was doing fine until now, it's showing some signs of disease but I don't know what and yes I did go to the disease and treatment forum for this. I thought I just want to share. Something I must have done wrong at the beginning to make all the fish died. I still don't know what the reason is. so frustrating.
