Coding a program in Python that would be able to take two user inputs of pH and TSS (total suspended solids).

tss= int(input("What is your TSS? "))

pH= int(input("What is your pH"))

Coag_dose = (tss//100)*2.5

if tss<= 100 and pH>=6:

print ("TSS is in acceptable range")

else: print("Increase coagulant feed by", Coag_dose, "PPM")

This is what I have so far.

I need it to tell the user to turn acid pH control on at a pH of 7.5-11. and to turn the caustic pH control on at a pH of 6-6.5 if the pH is below 5 and above 11 to stop operations and adjust the pH to 6-6.5 using either caustic or acid, depending on the pH. Any help?
