Hello, about 2 weeks ago after i did a water change, the tank would get cloudy during the day. It clears up by mid afternoon but every morning its cloudy again. I tried multiple things including a water change, adjusting the filter, and most recently i started dosing microbacter7 to see if that would help. Last night i saw some damage on my longnose hawkfish's right eye and this morning he was dead. I tested the water and nitrate nitrite ammonia and phosphate all came up as 0ppm and i noticed my ph went from 8.2 to 8. My calcium is around 400ppm because i stopped dosing after the cloudiness began. So im wondering what might be up with my tank so if anyone knows whats wrong or how to help fix it that would be greatly appreciated.
