    Anybody that can help me with info of gravity feeding a skimmer? How do you go about plumbing it, how much water does it need, any advantages , disadvanges?

    Any info will be appreciated.

    Most skimmers are gravity fed... Hmm....

    There is an argument that external and internal sump skimmers better than each other.

    Not sure if this is your question.

    Are you enquiring into gravity creating the " flow through" the slimmer or the gravity creating slow flow through a wave skimmer?

    I am talking about water from your overflow directly feeding the skimmer.

    I had water from overflow feeding skimmer..had a t piece with a ball valve on one end to adjust flow through skimmer. .was hard to set initially but once dialed in it worked like a charm

    :thumbup:

    It is ideal to skim 100% of your water filtltration turnover 24/7. for skimmers considered " external" skimmers. By this I refer to skimmers that are directly fed from the overfow.

    The choice of skimmer and return pump will determine the efficiency to the tank bio load. Note I did not refer to tank size or volume of water. :m106: skimming is totally related to nutrient export. All filtration should consider the expected nutrient export and residual nutrients that the system needs to feed corals and life within a system.

    Directly feeding a skimmer and any small fish that goes over the overflow will be chopped up. Ensure that the overflow is adequately protected, keeping all snails and fish in the display.

    I think the biggest concern for me was that the feed from the overflow periodically disrupted the skimming consistence of the skimmer if bubbles blew through.

    You can still prevent fish going over .

    So it seems to me as , that even if a skimmer is designed for gravity fed, it is better to use a pump to feed the water?
