Double the bubbles?

Right now I am bubbling 1 bubble per second of CO2.

My pH after 7 hours of this injection rate is about 7.5.

My KH is around 24 dKH (430 ppm).

So, I have about 22.8 ppm CO2.

Would I get 45 ppm CO2 by doubling my bubble rate to 2 bubbles per second?

Or is there some sort of exponential water chemistry thing I'm unaware of.

I just don't want to fry my fish with too much CO2 but I know 45 ppm is safe according to the threads I have read around here. I believe 35 ppm is optimal (eg. plants can't use more than that)

Regards,
Barry

Nothing exponential. You'll get double ppm or less, depending on your reactor.

how are you diffusing the CO2 in the tank? Do you have alot of surface irratiation? What size tank just to have a little bit of judgement on your levels of CO2 that your are injecting

You will probably get less than double since it would take more time to dissolve more co2 and some of it may fully dissolve before it comes out your reactor or reaches the surface.

are there bubbles comming out of the spraybar? Just trun it up a little at and time and check the PH every few hours. Dont turn it up and leave for the entire day. Just watch the fish and if they start gasping turn it down a little

once in a while a very tiny tiny bubble but for the most part the reactor seems to be doing its job.
