I don't feel I'm being dramatic. I have lost half of my fish in 3 days =\ I consider that quite dramatic as I've never experienced this before. The tank is like a death zone and currently is not enjoyable, I am therefore coming to the end of my tether!
Yes I've done the water change and added the meds to the water changed. Can't seem to get this cloudiness to shift, it still looks milky and the Platys are just lying on the floor seemingly waiting to die =\
And no, have to wait until tomorrow to purchase the new filter, which I will transfer the old media to so hopefully I avoid having to cycle the tank all over again.
