    What are the benefits and drawbacks to running filters in series?

    Less flow, more clogging.
    You get better flow and less clogging running them independent.

    So basically no real benefits?

    I disagree that there are no real benefits. Filters in series will affect performance as they clog. If the first filter clogs, it affects all downstream components.

    If in parallel, the flow from the clogged filter will swap over to the unclogged one if setup that way.

    Even if not, the clogging of one filter will not impact the other if in parallel.

    BIG difference.

    I meant no real benefits of running them in series rather than in parallel. :)

    I ran an Eheim 2128 then a 2229 in series for several years. When I switched to running parallel, flow improved and there was no increase in detritis in the 2229. So, I'd agree that having filters in series gains nothing. Flow is more important in planted tanks than what was once thought. Not such a CO2 loss penalty.

    If you are in staged micron filtration.........then perhaps.........

    Otherwise, I see little benefit.

    That makes sense.
