check your water quality with a reputable dealer or whereever you would buy fish locally my ph went lown to 7.9 and i brougt it back up with a buffer seems fish waste will help take your ph down also

Usually when you have a full load of fish your pH is something that you have to always watch as well as your nitrates.
Later!
