Can ph drop from CO2 kill fish?

My ph is around 8.0 normally. If I introduce 30ppm of CO2 then my pH should drop to around 7.0.

How fast does this drop happen? Won't this kind of flux in pH shock and possibly kill the fish?

Regards,
Barry

no. typically it takes an hour or two. If it only takes 15 minutes for you, then you are using too high a bubble rate.

Just remember to keep something in the filter to keep the KH up. But if you're (just kidding) if your standing water is 8.0 I imagine you'/ve got plenty of calcium or the like in the water to maintain the KH & GH.

I add oyster shells or sea shells or crushed coral to my filter to maintain my KH/pH as CO2 will use it up. Probably you already know this. bob
