I just purchased a used 165 gallon with 2 Eheim 2227 Professional filters. They are wet/dry. My question is, can i mod them to do away with the wet/dry system, and just run them as a continuous filter? They tend to leak through the air chamber when turned off (aka power failure) and this chamber is put under pressure. I want to completely do away with the air/float chamber. Any ideas on how this could be done?
