I did a 100% water change last Sunday because my ammonia levels were high. I noticed that my water has been slightly cloudy since the change and I have had a film on the top of the water that I keep scooping off. There is also a slight odor that I notice when I open the tank. All of my water parameters came back normal expect for my water hardness, which came back as hard (I have never had water hardness problems before). I have pH increaser right now, will that work to soften the water?
It is a 29 gallon tank with 6 neon tetras and 1 male betta. It is filtered and the temp stays between 79.5 and 80 degrees F. I plan on changing the location of the filter to see if a different location will create a better current. Any suggestions/ideas would be appreciated!
