AZMSGT, you said
"Any CO2 in the home will drop PH.
This is a large reason why the reefs around the world are dying. To much CO2 causing PH to be to low and creating acidic conditions. "
None of the links you provided support what you are suggesting! There are no reefs dying due to ocean acidification.
This is only an hypothesis of what may happen in the future, and its a hypothesis based on incorrect assumptions.
The suggested fall in pH unit of 0.1 over the past 200 years is not a measured value, its a calculated value using a computer model, again based on incorrect assumptions. They do not know to any degree of accuracy what the pH was in any area of The Great Barrier Reef 200 years before now. It may have been higher or lower. But it most likely would be somewhat different to now due to natural processes other than atmospheric co2 levels.
The effect of intermittently high levels of indoor co2 on the pH in any aquarium varies from system to system depending on how each system is set up because this changes the processes taking place. For example, my pH does not fall with intermittently high indoor co2 levels because the algae scrubber I use is very effective & the algae assimilates the excess co2. And the limited processes in dealing with co2 in any aquarium cannot be compared with the far more complex processes taking place in the ocean.
Consider this; you're suggesting that high atmospheric co2 levels will significantly lower surface water pH to a degree where calcification (the forming of calcium carbonate structures) will cease & calcifying organisms will die.
This graph is interesting. The white boxes - A, B, C, D, & E, represent known
Major reef building episodes by calcifying organisms over the geological timescale. The black line represents atmospheric co2 levels & the blue line temperature.
Note box A & B in particular. Despite atmospheric CO2 levels above
5,000ppm in A, & as high a
4,000ppm in B, reef building organisms were able to calcify without any problem.
Box E represents the major reef building period of the corals we have today, the scleractinian corals, with CO2 at
2,000ppm.
Interesting is the prediction that co2 increases will cause ocean acidifciation, lowering pH & greatly affecting calcification.
This record destroys this theory & shows that deep ocean up-welling & surface organism primary production controls ocean upper layer pH levels, not atmospheric CO2 levels.
