    Hey SM.. Just a thought for this model.... If you make the discharge of this unit higher it would take unfiltered water in through the bottom and the clean water would come out up higher that way more unfiltered water would enter through the bottom only. The way I am looking at it the filtered water will come down and mix with the unfiltered water on the input of the scrubber...

    Or did you design it like that?

    Just a quick pic I changed on the bottom left of yours so you know what I mean..

    Water flow seems to not be an issue (yet) with a UAS... maybe because of the larger amount of water around the growth.

    Your outlet would sort of do what you say, but it would let a lot more bubbles get in the tank.

    SM, My scrubber is working fairly well, cleaning about every 10 days, but I am still seeing algae growing in my DT. My Nitrates are 0 and Phos is around 0.25. If there is no nutrients for them to eat could the lights cause the algae to grow? I am about 1/2 cube per day and my screen is 5x5. Using RO without DI and the TDS is around 5. Thoughts?

    How much are you cleaning off the screen, and where is the display algae growing?
