Natural vs Unnatural Methods

[Randy Holmes-Farley]

UV in lights yes. But UV-C sterilizers use 254nm that I think doesn't get through the atmosphere.

Yes, good point. There's almost no 254 nm light getting to marine organisms, even bacteria. Let's move that to unnatural.

Wouldn’t rain wash it back into the ocean? So not completely removed.

Could depend on what tide cycle it was in. If it occurred during high tide then less of it might find its way back into the ocean. Also high winds can carry it up into the dunes where it would be trapped. Plus as the rain comes, the waves are still rolling and roiling to churn it up an re deposit it into the beach. I’m sure a portion returns, but IMO the surf is natures skimmer.

CO2 scrubbing through soda lime: unnatural.

Imagine how much it can help coping with climate change and ocean acidification if this takes place in nature.

It does. The water values we have in the oceans is depending of the balance between Ca, CO3- and others.
Every day when an algae dies and sinks and incorporates in the mud in the deep CO2 is taken away.
And then in 100 000 of years it will be oil and gas and we take it up again and burn it to CO2 again.
Sounds like a perfect natural cycle doesn't it?
The only problems is that we take up in tens of years what took 100 000 years to form.

Next year I plan on drilling in my tank to try to strike oil.

ATO? Natural or unnatural?

Natural ocean analogue could be evaporation and rain.

Unnatural part might be that we don't tend to capture our evaporation and re-use it.

*likely not the kind of thing you were looking for,,, but oh well

Capture evaporation and reuse it => the LID does it.

ATO => Rivers.

This is true. But it's a biotic process. While for CO2 scrubbing using soda lime or calcium lime, there is probably no parallel in nature.

On the other hand, algae as carbon sink, sure! This will be more akin to running a refugium/algae scrubber to increase pH in the aquarium.
