Current status of CRS tank

Picture below is of my Orange Dwarf crayfish, Pumpkin Pie 2, and has absolutely nothing to do with my CRS tank.

Temp : 71 degrees

Ammonia : None

Nitrite: None

Nitrate: None

PH: 7.6

Shrimp tank perimeters are doing fine except PH is too high. Must figure out how to lower PH.

Possible solution: small water change and addition of another CO2 component.

It is now time for me to cuss in frustration.....

FUCK!!!!!!!
