Water quality levels

[Dallas E. Weaver, Ph.D.]

Greg,

What is "optimal" depends upon the details.  For example, if the nitrite 
is high, you want high chloride while maintaining a reasonable Na/K 
ratio.  

In general,  5 < DO < 10 with total gas pressure < 1 atm Ammonia, 
nitrite non-detectable ( < 0.1 ammonia, < 0.05 nitrite). TDS < 2500 ppm 
for breeding and larval and < 5,000 ppm for growout. pH from 6 to 8 for 
breeding.
