My 10 gallon tank is cycled....been a couple months now. A few days ago the water got a bit murky looking. Water params are where they should be, no new fish, decorations or substrate. I vacume and change 25-50% water each week. I have 3 cory cats and a betta fish in there. I can't think of anything i did differently. What the heck could this be from?
