Connecting filters

I donít plan on doing this but I was wondering if anyone has or what advantages and disadvantages it would have to connect two different canisters through the output to the input of the next.

Would the pumps help push/pull the water through each other? Or would it just have less flow

I cannot see an advantage for doing this. Assuming that each filter has its set of coarse, medium, and fine mechanical filtration layers, then particulates and debris would be trapped in the first filter and never make it to the second. If the second filter had only biological media, then thatís fine, however, more media does not always mean more beneficial bacteria (as they are limited to the amount of nutrients present).
Disadvantages would be the output of the first filter will most likely not match the intake of the second filter. You will end up with either a negative or positive pressure situation. Also, should one of the filterís motors fail, then (depending on the design of the impeller housing) it could impede the flow overall.
You are better off just running one or both (one would act as a failsafe).

I agree with Fresh2o. There is no benefit to connecting two filters together especially two different filters as you said. If the filters are different you will most likely have to different gph which will be a problem. I would run them independently.
