    Probably big. But you can try both.

    I have som kind of color and growth for a couple of days, it is difficult to define the growth and color because of the location of the screen.

    I also have snails eating from the screen, they love it . I think "in tank" scrubbers should be constructed snail safe.

    Hmm, a couple of big snails are making race tracks on the screen

    You can put some mesh around it.

    Is that a bad thing? I say let nature do what it will. Maybe we have the first 100% "clean less" scrubber, or at least as long it's groomed well, clean when needed...

    No, you need to get the nutrients out of the tank.

    Hello!

    I give the snails another week, if it still is a problem i will enclose/make a box to put the screen in. It will still be "in tank" though.

    I have some kind of growth, not like the growth with the waterfall scrubber. The screen seems to fill up with some kind of fur, and it is even over the whole screen, it is the same fur in high light, low light and backside area of the screen. Just short growth, but it is there.

    It will take some time to figure out the best running conditions. The waterfall version went for a year or two before it was realized that you need stronger light; until then it only grew dark brown or black.
