I have a goldfish and I am going to transfer him to a new tank. I know from previous experience that the water should have gone cloudy and returned to normal before you put them in (nitrogen cycle needs to happen) However, my tank has been up and running for longer than I normally leave it, I have put in filterstart, and a few other products, but it hasn't gone cloudy yet...i have also put in lots of water from the current tank, and some old filter media and gravel to kick start it but nothing! Is it safe to put in my fish? thankks
