    Actually, today is the 8th day since last cleaning,
    this is the LED side, the CFL screen (still 'scrubbing') looks about the same:

    The flip side, 8th day, LED lit:

    The CFL lit side still growing well! I'm assuming this is what they refer to as '3D' growth.
    It's think, with a kinda of honeycomg appearance to it. It also has long stringy bright green growth,
    that also gets caught in the cage of a MaxiJet PH I have in the sump to keep the bubbles away from the RP intake.

    This is my CFL lit side after ~13 days while it still hangs in the pipe, water flow off for the pic

    Here is the bottom thru the sump glass of some of the green stringys

    MY LED lit side is also doing well, I'll clean it next week, alternating so each gets cleaned every 2 weeks, one week apart.

    You can really only get 3D growth if you have an enclosed growth chamber that allows the algae to get suspended in water that builds up

    I'm still not sure what exactly that means.

    Are you saying that the screen is suspended in to layers of glass/plastic real close? I have a lot of flow over my screen, more that most videos show.

    if the algae gets suspended in water that builds up, it'd be underwater. Seems like less light would get there, etc.

    My last pic l.ood pretty 3D to me- it's not one this sheet, it's a real think honeycomb like structure.

    You can also get 3D growth by attaching strings or rails to the screen, so the screen sticks out into the flow.

    The best way to explain this is with pictures. So here is the beginning stages of 3d growth, in this pic the algae has grown long enough to form a mat on the bottom panel

    If you let this continue, it just keeps building up and trapping water. The algae gets partially suspended in the water and this allows light to penetrate deeper into the growth - with an open-air screen, you can't get this.

    Same point in the process:

    A little further along (water shut off in this pic)

    Similar growth but before shutting off the water

    ^^ this is the one on my tank, it sits on the rim of the tank and in order to make it run without dumping bubbles into the tank, I have to choke back the drain quite a bit, so the water level build up a lot faster in the box vs the one below, which is over a sump. But you can see the 3D growth still easily occurs whenever you have a narrow growth chamber (about 2" across with the screen in the middle seems to work well) and a bottom panel that allows water & algae growth to pool in some fashion

    TY Bud, excellent explanation, with photos

    Doesn't that require waiting a longer interval between cleanings though?

    Not necessarily, it depends on factors like tank load compared to screen size, flow rate, lighting intensity & photoperiod, and growth chamber dimensions.

    For instance if your growth chamber is 3" wide vs 2", you may never get 3D growth by day 14 or even longer. If you growth chamber is smaller like 1.5" then you might start getting it sooner.

    Regarding letting it grow longer, that's what you want. The longer the algae mat can be left alone to grow with without the roots/base dying, the better because the growth is not linear, it's not quite exponential but there is an exponential stage and one of the things that slows that down is shading. The limitation with an open air screen is that you get shading, 3D growth reduces this.

    So then the long strings that hand down in my sump and get caught in my flow generator power head would be considered 3D sort of?

    By strategically placed power heads in my sump, eliminated air bubbles thru the RP and into the DT.

    um...maybe?
