I have used the overdose method more than once on different tanks. Works everytime. I also dose every day. Until I start to see the algae start to turn white.

I got scared off after two doses- my CO2 indicator responded quickly from a dark blue (low) to a bright yellow (too much). I didn't want to kill the fish... was there something else at work here? It seems to have been a pretty major swing.
