I am interested in the idea of a sump for my planned tank. However i have some concerns. Could i not use a wet dry and instead just use ceramic media between baffles to force water through the media. I have heard wet drys are best as the bb receive the most oxygen. However wet drys pose problems for CO2 loss. Without a wet dry i would not have this problem, or would degassing still be a problem with an external BeanAnimal overflow. To generally increase oxygen levels and specifically near the bb could i not place an air stone beneath the media. So experienced sump users please tell me what you think, thank you!
