Still love this man. He was a saint. No one could preach racial diversity without coming across across accusative or judgemental quite like this guy could.

Everyone: Obama's presidency was drama free.

Me: He literally murdered US citizens without trial or due process. It was kinda a big deal

@mngrif Ahh yes fully aquatic plants absolutely need injected co2 in the light phase, I see why you said that now. terrestrial plants are different sorta.

With all plants (or anything in general) if it produces energy from light then it consumes CO2 to do it (as you know) and if it consumes its energy (sugar) instead of light then it consumes O2. so during the light phase it consumes CO2 and dark phase O2.

But thats an oversimplification. In reality the sections of a plant that produce the sugars (any part that is green) will consume CO2 when light is present. But since the roots 24/7 consume sugar and do not produce their own energy all roots of all plants need O2 and not CO2.

Since an aquatic plant has its whole system underwater whent he light is on it needs more CO2 overall than O2, when the lights are off it needs O2 only. But since terrestrial plants have their leaves out of water and the roots in water they would 24/7 need oxygen only injected into the water. The need for the CO2 int he green leafy parts would obviously come from the air.

So at least in that sense they may be a bit easier to care for than traditional aquatic plants.

@mngrif BTW i assume you meant O2 starved. Plants roots consume O2 not CO2, only the leaves consume CO2 mostly, though even the leaves switch to O2 when lighters are off.

@mngrif Ive done a lot of pure hydro but there will be some unique difficulties with fish. To increase root O2 for plants just add a little hydrogen peroxide. But actually degassing the CO2 in the water itself, i dunno. I was under the impression an air pump will usually inject O2 and since this competes with CO2 in terms of dissolving it, it should cause the co2 to more readily leave the water.

Similar to how in the lungs similar mechanisms work.

Rgardless if it just comes down to surface area I would think that could be solved easily enough with some creativity. A waterfall or neblulizer of some kind running constantly would effectively increase surface area.

@mngrif My dream, assuming i waste infinite resources, would be to have a tank some 4 - 5 feet tall and just as wide. Ideally all transparent but thats asking for a lot. I would then have some sort of fish in the water, hydroponic plants with root systems going into the tank with the fish, and an extremely agressive ant colony as a small island in the middle, with interconnecting transparent displays fo rthem as well (under water but water tight.

Assuming I get a species of ant that cant traverse water very easily the water should act as a natural barrier for the ants. If they are aggressive and i have semi-aquatic creatures as well i might get the ants to occasionally eat them. Ideally creating a somewhat self sustaining eco system.

Right now its little more than a pipe dream. But that would be my ideal mega-project.

@mngrif yea im considering a lot of options. Sadly anything completely transparent is pricey. But im thinking of alternatives like epoxy resin walls.

Interesting fact of the day: If you make 15 US dollars per hour or more, and work full time, you are statistically in the top 1% elite in terms of earning power.

@mngrif I've been trying to come up with a way to make an affordable ultra large aquarium...

@amic Best of luck! Sounds like a shitty situation :(
