I am curious as to how you apply this to the system.
Citric acid and ascorbic acid (vit C) are 2 completely different substances. Citric acid is toxic as certain levels to aquatic organisms whereas ascorbic acid (vitC) is not.

That's why you've heard of people using citric acid as pH down only to have dead fish in a few days blaming it on a pH swing... LOL!
