Aquarium Advice Addict
I have a 29 gallon tank that includes three calico fantails and one fantail koi, and before people start giving me the speil about my koi its just in my tank until we build the pond for it its only two anda half inches so don't worry about it being too big for the tank. Anyways on to business, my tank is a planted tank and the problem I'm running into is that after my 40% water changes every 5 to 7 days by the third day my tank is cloudy again. Is it because of my goldfish? Because I also have a ten gallon tank with three guppies and that water is crystal clear. Here are some before and after pictures
