    80 gallon tank filtered with Eheim 2217 heavily planted, low tech,non CO2 with low light plant's and approx 45 fish.
    Have been dealing with this white surface scum for a couple of weeks and yesterday,I slapped a Emperor 280 on the opposite side of return from spray bar and within an hour,,the slick had disappeared. Is no media at all in the Emperor just increased flow near the surface.
    Two questions, How critical is flow in non CO2 tanks and.. has anyone tried hooking up two spray bar's to one canister, or should I perhaps Add Koralia 2 near the surface to replace the Emperor or get a larger Eheim?
    Okay,more than two questions.
    Many thanks in advance,
    Lee
    P.S. Appreciate thought's on causes of afore mentioned scum.:confused:

    I you not using a liquid carbon then you blowing the only carbon source (how low the level may be) out of your water.
    So you can continue this heavy surface movement and add liquid carbon or go for a skimmer.

    I have no experience with two spraybars or Koralia's.
    I use a skimmer.
    This the one I use

    I do indeed have surface movement,but water level is high enough that the surface of water is not broken or no waterfall effect from water returning to the tank.
    Have considered a skimmer but still undecided.
    Liquid carbon source is out of the question for 80 gallons due to cost's involved.
    Thanks for response!

    Surface scum is a bioprotein layer, if it's green and sticks to your finger. It's caused by heavy organic loading. you can do the following:

    1. Remove as much as you can manually
    2. Clean your filter, this could be the cause.
    3. Replace 75% of the water
    4. Move the surface.

    That should get rid of it.

    if it's just a kind of grey misty layer, a surface skimmer will cure that.

    regards,

    Thanks dutchy,
    Cleaned the filter this past Sunday,is indeed white to grey film. Not much liking the Emperor filter's presence aesthetically, so may borrow powerhead from loach tank and aim it towards the surface for some more movement.
    if that doesn't work,I'll add the skimmer.

    This grey layer is very hard to get rid of.
    Only have surface movement or a skinner helps.

    I am still not sure what it really is read. There different opinions about it.

    Hi,
    i found this to be a problem when i use frozen food, dry blood warms, poor quality food. Have you started using different type of food?

    Yes,I have placed a powerhead on the opposite side of the spray bar from canister .Both are just under the surfrace.
    I too have heard varying opnions as to what the primary or cumulative cause(s) could be from too much light, (doubtful), 36 watts x 2 6700K CFL to to perhaps nutrient depravation of some type. I am not adding CO2 other than what is created by the fish and organic breakdown in substrate so perhaps too many fish or not enough in NON CO2 tank.
    I am the only one that really views the tank but do find it unsightly

    No frozen foods offered, mostly Ocean nutrition flake ,with New Life Spectrum pellet food, along with freezedried blood worms perhaps once a week or two.

    skip the freezedried blood worms, do a water change by placing the end of the hose near the surface so you will be suking both air and water/skum and see what happen? freezedried blood worms can do this.

    Good news. The addition of the powerhead, which creates a little more movement just under the surface,has appeared to alleviate the problem.

    I had surface scum as well. I added the Eheim surface extractor to the filter. No more scum.

    I used to have the same problem. I just added a couple of mollies. I'm not certain if they actually eat the stuff or if it's just because they like to hang out near the surface and break up the stuff just by moving around.

    Oh yeah, and the scum I had was the whitish kind. Not the green kind.
