    Do continuous automatic water changes REALLY provide any benifit?

    Some of the new systems are moving away from water changes entirely but that's it my question.

    Is continuous small water changes REALLY a more beneficial procedure than batches water changes?

    Any research or videos (a la BRS investigates or Randy Farley write ups) anyone can link me to...or is it just anectdotal?

    The advantage of many small water changes over one large one will be more stable water parameters. I remember reading that using AWC over the 10-15% weekly change is slightly less effective at transporting NO3 and PO3 out but the difference was negligible. In the end it comes down to more cost and work up front for what is an automated system vs lugging water in and out. http://www.reefkeeping.com/issues/20...f/index.php#10
