    B.S.

    Todays the day I start my Bacterial Scrubber. Gonna be simple to get experiment going;

    1) clean skimmer and pump with HCL.
    2) rough up screen in form it into a cylinder, to go neatly into the skimmer body. Perhaps heat it to form shape.
    3) fix my air pump to the DIY co2 generator and feed skimmer with the enriched air.
    4) put coarse filtration foam in collection cup so the the drain doesn't get blocked.
    5) turn it on and see what happens.

    Pictures later

    Your first thoughts may have been accurate. Only one way to find out though !

    Ok roughed up my screen, using my favoured method (steak knife);


    Feel a bit guilty about cleaning the pump and skimmer, after all, these critters are probably cleaning the water more than the skimming action. But gotta get rid so I can see what's going on inside, if anything.

    Pump;


    Skimmer body;

    Science project. Cool.

    Skimmer people would be very upset with you. And maybe even tell you you're going to kill your tank.

    Well, mop and bucket on standby. Connected up. PH drop of 0.1 at skimmer outlet but equalised in sump.

    Quick update - this co2 injected skimmer is very effective at reducing the pH of the sump. Now the DIY generator is in full swing, the pH of the sump dropped to 7.6 (from 8.2). So now set the pH monitor to keep the pH of the sump at 7.9. Have tested the display and that's still at 8.2ish, so no worries there. This does mean that extra co2 is getting to my ATS screen, hopefully not enough to induce slime on the ATS screen though, I want it in the skimmer ! I have noticed that a few minutes after opening the cabinet doors to the sump, the pH goes up. The only reason I can see for this is that some of the Co2 is fizzing out the top of the skimmer and then sitting on the sump surface, when I open the doors this blows it off the sump, I'm open to ideas though.

    Feed the ATS directly with water from a calcium reactor setup with no media. The calcium reactor (or any inline CO2 injector) should use less CO2 by dissolving it more efficiently into the water than the skimmer; and don't give the CO2 enriched ATS feed water any exposure to the room air until it's on the ATS screen.

    Growing slime - its about 10mm in patches. Looks like the bacteria you get when dosing vodka. I wonder if it will skim out ?!?

    Now it's taken hold of the top third of the screen, this stuffs growing fast. Anyone know if I can just dissolve it in Hydrochloric acid and test for nitrate and phos ?
