this weekend i was up at my camp and i went along the creek and got little rocks out of it. made sure they werent sandstone or shale. I came back and boiled them n put them in my tank. my tank has been cloudy lately n when i put them in after i changed my water my tank is still cloudy and my jag is acting different then before.. i was wondering if this is becuase of the the rocks i put in n if it isnt good to have them in..
