Increasing CO2 is good for sea life, according to Dr J Floor Anthoni

AGW believers keep bringing up ocean acidification as a possible problem with increasing CO2 in the atmosphere. Dr J Floor Anthoni doesn't buy the alarmism. He runs Seafriends, which has a Sea Conservation website out of New Zealand. I found his website, Seafriends.org.nz, recommended on the Geology.com website.

"Opening with these thoughts, the (bio)chemistry of the sea is so complicated and unknown that the scare for acidic oceans is entirely unjustified. "
...
"As far as the science of ocean acidification goes, there are some major errors and conflicts, and the amount of missing knowledge is much larger than what we know. Scientists have uncritically accepted the findings of the IPCC with critically low 'pre-industrial' levels of CO2, but has anyone tried to grow plants and seedlings at 180ppmv CO2?"
...
"What annoys me is that an entirely hypothetical threat is blown up out of all proportions, while at the same time the foremost threat to our seas, that of degradation (eutrophication), remains insufficiently acknowledged and investigated. In the world's degrading coastal seas, many questions can be studied that also relate to ocean acidification, for acidification is also a symptom of degradation. What is the main threat to the world's coral reefs - hypothetical decalcification or actual degradation?"

He says that increasing CO2 in the sea is a good thing for sea life:
"The most important limiting factor in aquatic ecosystem is the dearth of hydrogen ions (H+), which has also been overlooked. The more acidic the water, the higher biological productivity becomes, and the denser the amount of life. In the sea this is borne out by the observed fact that highly productive upwelling areas are more acidic [note 1 below]. In other words, acidic seas are a good thing."
...
"Note1: In upwelling areas, cool deep water reaches the photic (light-) zone. This water is more acidic and it also contains nutrients. Those nutrients were produced from sinking biomatter that became decomposed by bacteria, in the dark underneath the photic zone. As the nutrients became available as soluble salts, also the water became more acidic (less alkaline). In the process, also more CO2 dissolved into the water. When the deep water reaches the surface, the nutrients start plankton blooms which also make the water more alkaline, which in turn limits productivity. However, it is observed that upwelling areas remain relatively acidic, thereby promoting productivity. It could also be that a high turnover of nutrients, possible by active planktonic decomposition, lowers pH in upwelling areas. "
