lazy... or is there really a need, to do it weekly... water change schedule...

Hum. You know that in nature co2 is never injected into the aquarium and frequently the 'bug' count is a bit higher than we would like in our homes.

Sure, but we try to compensate for how little our glass boxes can do, in terms of processes, compared to even a tiny stream.

My Parananochromis brevirostris came out of a stream we couldn't see into. They were caught with blind netsweeps of the shore roots, as the river was polluted by gold mining sludge.

Granted, that's not natural, but I ran UV on their tank when I got them here, in case of bacterial problems. The mining must have just started, because they were fine. Their habitat wasn't. What survived survived if the gold miners moved on to kill elsewhere. If I had money to invest, it wouldn't be in gold.

The streams we took fish from were generally drinking water for local villagers. That made the pesticides from corporate farms/plantations and gold mining run off and mercury doubly tragic. But before the rivers came under attack from people, they were clean.

However we achieve that, it's what we should want. Clean water.

No clue how that is relevant to injecting co2 in an aquarium but whatever.

In nature is such a wide field...
Nearby springs here in Germany, you can measure 70mg/l CO2. No fish, lot of swamp plants as you can imagine.

But inside an aquarium, we need a lot of fast growing plants for different reasons.
-They deliver oxygen
-They are part of the "biological filter system"
-Plants are surface for good bacteria
-Their roots help to clean the substrate
-They look fantastic

No offense but I think this is insane logic. these aquariums have no injected co2:

Don't get me wrong - if you want to inject co2 by all means inject co2 but don't pretend you are imitating nature or improving the environment for fishes.

As for plant growth I think the above 3 aquariums demonstrat that plants grow plenty fast without inject co2.

Nice! All I can do is kill plants and grow algae.

I personally refuse to add anything that is poison to the fish, yet my tanks are jungles... I just have to choose wisely on which plants
