Planted Tank Myth Buster Thread, a compendium.

[pejerrey]

I want a make a small compilation of myths in planted aquaria. Like heating cables, phosphate causing algae, ugfs, etc.

Feel free to post new myths, links to discussions and also to ask questions.
Back it up!


This is to use as a reference for future discussions.

I will start with aeration, oxygenation.

How does an airstone provide o2?

Is an airstone better than a spray bar creating a ripple in the surface to provide enough o2? (or vice versa)

Can it be too much o2? PR??

Will it eliminate co2?

Thanks.
