    I debate whether or not to send this excellent video out to my friends. Should I let the ignorant be ignorant still or should I let them on the truth?

    The antarctic circumpolar current cannot all squeeze through Drake Passage so you get cold deepwater upwellings along the coast of Peru. That water has a PH of 7.8 which is amongst the lowest oceanic water PH other than coastal waters effected by land runoff water. (Dr Patrick Moore.)
    Higher co2 absorption by oceans manifests in greater uptake by coral, weeds and algae etc which is photosynthetic.
    Them coccolithiphores really love their co2 and generate limestone. The white cliffs of Dover was once all sea critters.

    When I used to keep fish tanks, the first thing to do is go and collect a bunch of sea shells and drop them down the bottom. If left to itself, organic breakdown of waste products gradually turns tank water acidic (unrelated to CO2) and having some solid carbonate in the tank will buffer the acid. You can also buy fake “shell” shaped blocks which slowly dissolve and do the same job.

    CaCO3 is only slowly soluble in water and as it dissolves, KH and GH increases. So it can take a few days to dissolve depending on the pH of the water. As it dissolves, pH increases therefore reducing the dissolving rate. (If the pH is above 7 then the dissolve rate will be slow). The surface area of the material will determine the speed of dissolving. So smaller pieces dissolve faster.

    When you add CaCO3 to water, it reacts with any acids present and binds with free H+ ions to form Calcium bicarbonate, or Ca(HCO3)2 and thus reduces the count of free H+ ions which raises the pH.

    Over millions of years, plenty of shell grit, broken corral, snail shells, cuttlefish bones, and solid carbonates have collected around beaches. There’s also limestone (formed out of ancient shells) and chalk (also from ancient shells). The available buffer against acidity would be massive. Calcium is the fifth most abundant element in the Earth’s crust … we are never going to run out of Calcium.

    This simple chemistry used to be taught in high school. That’s where I learned about it.

      And that’s not the only one. For example, there’s magnesium, aluminum, iron and a whole lot more. These have different solubility constants (in lab water) as well as in natural water (which is *never* pure water), and these also depend on temperature (internal kinetic energy), pressure (a reflection of same) and the kinds and concentrations of the other (all?) species present.

    “Table 3 shows the different range of pH some countries are implementing. Generally, all
    countries use an average range of between 5.0 and 9.0 in freshwater, and 6.5 and 9.0 for
    marine, all of which are within the limits of optimum fish production”

    Interestingly I contacted
    Kim Fulton-Bennett @ the Monterey Bay Aquarium Research about the using the term acidic Vs the proper term less base.

    Kim’s reply.

    “Yes, “less basic” would be a more appropriate term. However, it would also be very confusing for members of congress and the general public’

      Realization that one has been intentionally deceived can be very confusing.
