Ugh.. so i have a 27 gallon tank i think and i had it set up for a couple months. Well i had a couple fish die on me so i tried to fix my ph balance myself.. So i bought this kit from meijer. Some how i messed it up i think and not only did it not really work.. but it left this cloudy film on the glass that i CAN NOT get off.. Anyone have any ideas what it is?? Calcium buildup??
