Does anyone agrees on this??? Regarding Co2 in CRS tank....

Aquatic animals are not affected by pH as much as we think they are. Animals that live in water (fish, shrimp, crayfish, etc.) have osmostic-regulatory systems that govern how much water enters and leaves their bodies to keep them at a state of equilibrium. Equilibrium means that the animal can excrete waste (not necessarily poop) from their bodies as fast as they can take water in. The most important factor is TDS (total dissolved solids), which in its simplest terms in the combination of KH and GH (but it is actually more than just those two). If the TDS remains constant and you inject CO2, the animals in the tank will not even notice any fluctuations in pH regardless of time of day. What is important is the state of equilibrium the animals maintain due to TDS. Does that make sense?

Wah bro you like asking some math question like that. Too difficult to answer.
