    Dimming is a good idea.
    Not only do they last longer, but they are more efficient as far as lumens/watt.
    And yes, that is a good way to spread out the light.
    Of course, you pay more. Dollars per lumen goes up.

    As far as my LED system, I am still quite happy with it.
    Well, except that recently it switched to a tougher algae. I thought it might be bryopsis,
    but looking more, I think it is just a mix of turf.
    I don't get a ton of algae, but that is because I don't feed much either.
    At one cube a day, plus a few flakes, you can hardly expect pounds of algae every week.

    I was talking only in terms of algae, not electronics.

I just looked at your nano scrubber, single sided, so ya, 5 or 6 LEDs at 1" distance on your scrubber would be my recommendation and run them at 400-500mA, which means you would want to get a dimmable driver like a Buckpuck that handles up to 6 3w LEDs.

    Or get a bigger driver and it has a built in power supply

    Hello!

    Thanks for your time looking in to my question, and scrubber setup.

    I am setting up a new nano reef this fall, this nano reef will be about 120-200 liters of water. I am going to build a new scrubber for this nano reef and thinking i will use leds in this scrubber, thats why i asked about the distanse between leds and screen.

    When it comes to my current scrubber setup for my 63 liter nano reef i am just about finished with a new nano scrubber for this tank. This scrubber is lightned with a 1xPL-24W bulb and eksternal driver, I will post a building tread for this new scrubber this week.
    Here is a link to the bulb i am using:

    Re: Ace's ATS v2.0 - LEDs

    Quick update showing how it is working today.. This is a 5 day cleaning, I cleaned it on Sunday and it is now Friday and this is what it looks like before I cleaned it. Pictures of the screen don't show how it truely looks in person unfortunately. It was very thick (3D type growth) and very heavy holding the screen. I see more growth with 6 reds + 1 blue than I was getting with just 4 reds. Not sure how much the blue helped though since I made 2 changes at once. I will say one thing, I get less growth since I took off a big fan I had over the screen. Now I just have 2 computer fans cooling the LEDs. So in my opinion, there is some limiting factor with algae growth that is overcome by adding a lot of airflow over the screen, although the downside to that is lots of evaporation and your heaters running a lot more, running up the power bill. I decided the extra cost in power wasn't worth the extra growth.

    Best LED growth yet

    can you show me what you used to mount the heat sinks? it looks like they are on some kind of bracket that allows you to tilt them.

    Re: Ace's ATS v2.0 - LEDs

    I just used standard 2"x1" C channel aluminum. I put some stick on rubber feed on the bottom ones to be able to tilt them and have them stay. The top one I just riveted a small piece of aluminum wrapped in electrical tape.. cheesy I know.. but it works.

    It is likely that the increased airflow was providing more CO2.

    Re: Ace's ATS v2.0 - LEDs

    Ace your scrubber design is awesome. I too will be radically modifying my ATS setup and wanted to ask you a question. I believe our screens need to be tougher in order to last longer. My 1st ATS used 2 of the typical screens sandwiched together with wire ties. After about 10 months the algae grew in between the 2 screen making the unit too thick for the slot. So I removed 1 screen and went to a single screen which is now torn in a few places. We need tougher screens, thinking of building one out of thin acrylic. I actually preferred the sandwiched method because you could get aggressive on the pruning and there would be existing algae in between the screens to easily grow back. Comments? Bill
