Mechanical and Biological filtration in different filters.

I think you may struggle with the aquaclear and CO2, only because of how these filters return the water, rather than a flow across the tank like a standard filter it pours down into the tank, this means the circulation of co2 might not be great. I would be sticking with the external as well.

It seems to be doable.



That's a 80 liters tank that seems to be running just with an Aquaclear 30. I guess the secret is to always have a high level water. So the CO2 doesn't flunctuate too much.

The secret in the case of the video above is it is Filipe Oliveira He understands aquarium plants and husbandry on a very high level. He could probably run a successful tank using a candle lol

I am not saying it's not possible, just that these filters are harder to work with than a typical external filter or filter with a traditional output. You'll also notice he is using a surface skimmer which helps with flow

Well, my girlfriend bought me the Oase Biomaster 250 thermo for christmas, so problem solved.
