Just to point out, what a lot of folks are unaware of, is the toxicity level of ammonia in different pH ranges. Ammonia is toxic at .5 ppm
, but when pH is 6.6-6.8 it's not nearly as toxic as when your pH is around 7.6-7.8. You could have .2 ppm
with a pH of 8.2 and lose everything. That's why no matter how great your parameters appear today, when you go to work or school or out for whatever and everything was just fine only to return and half your babies floating and not swimming. That's why with smaller tanks things can go downhill so quickly and WC
's make all the difference in the world.
