    Hi guys.

    My tank has now been running for a month and seems like my filter is properly cycled now however I still get this film on the surface.

    I have pressurised CO2 and at the moment only dose Flourish at 10ml twice a week. Which seems to be sufficient. And then i have ADA in the tank as well. But every night i get home i remove some of the surface water as the CO2 bubbles get stuck under the film and i am afraid that my fish might not get enough oxygen. Thus i only run CO2 when i am.at home to check what happens in my tank. Thus i am not getting the growth potential i am supposed to.

    This is so annoying!!!
    I will have to get a surface skimmer.
    Which brand can I look at that won't cost me a kidney?
    And why does this keep happening?

    Thanx
    Martin

    Most likely protein bio-film...if you aerate your tank during lights out...the surface agitation will more than likely break it up.

    DIY surface skimmer, works like a charm. The layer also decreases the light efficiency.

    I know but it didn't answer my question about the ADA so it did not help and where is the fun in being part of a forum if I cannot ask something that has been discussed before but the previous posts I searched did not give me exactly what I am looking for. And seeing that I feed minimal as there is minimal livestock in my tank it is not the food. And I dose Flourish and I did not read anything about that in the posts as well....
    But yes I will search more and ask less

    Ask away...as long as you dont mind the occasional post with a link to a previous thread every now and then :p

    Still happens to me as well...PLUS...every time you ask a new question, someone else might see it and use it.

    I run a airstone at night and works like a charm.

    Thanx Coldcat. I will probably have to install an airstone then. Do you switch the air off during the day*?

    Yes...as you dont want the surface movement during the day, that will cause gaseous exchange which will have CO2 "escape". During lights out/night it's fine...as both plants and fish take up oxygen...

    yeah It's on a timer. I have it turn on about 30mins after lights off, then run till 2 hours before lights back on.
