    Hi there!

    I am new to fish keeping and have a 75 gal tank with 4 koi that I just cannot seem to get right. The water is very cloudy after repeated water changes. I have even removed all gravel decorations in an attempt to get the water to clear up, but no luck. I also noticed today that it appears that 2 of the koi have lost some scales. Any ideas on what could be going on?
