I just set up my new tank today as i plan to start the fishless cycle tomorrow and as i filled my tank up with water i noticed it to become very cloudy (not sure if its from gravel as i did rinse it) Will this cloudiness go away once my cycle has finished? Also i tested my ph and its reading 8.4 and i need it down to 7.0 what can i do to reduce it? If it helps, glowlight and/or neon tetras and panda cory cats will be living in my tank.
