    I am planning on bigger tank. Should be 40 gal. Now it is time to decide what route to turn. After some time passed , can I get your findings regards waterfall vs UAS. What you would choose if you were free with your choice ? Either way scrubber will sit in back chamber. Be it waterfall I should not need addition of air pump.

    Im planning feeding up to cube so one side 10cm wide and 15 cm long screen should be sufficient ? This way I would need 80 liter per hour air pump ?

    Technically an upflow should be better because of the bubbles, but since you build your own, the bigger question is how you build and operate it. Easy of harvesting might be easier with an upflow too... just lift up the screen. 2-sided would always be much better, however.

    Yes 80 lph.

    You know, the reason why the algae uses the alk is because there is not enough cO2, im dying to try injecting co2 into the scrubber chamber, i wonder if it would really lower the ph of the water significantly.

    I worried about that to so I didnt, I even put a couple fans over the waterfall scrubber and didnt see any noticeable difference.

    It seems like everybody is using LEDs for their UAS... I know nearly nothing about LEDs because when they started getting popular I figured I'd let them get figured out before I looked into them. Now, I'm in a spot where I think I would benefit from them... At least for my UAS.

    Where can I get the best deal for some LEDs for a 5x5 screen? I don't think I want to do anything DIY for this as my free time is limited for now.

    Thanks!

    Floyd has good luck with rapidled and I use topledlights from ebay but, I get my drivers from rapidled lately as the topledlights has been out of the driver I really like to use. Rapidled even has a section to show you how to build a DIY unit.
