DIY Turf Algae filter

Rating: 3 votes, 2.33 average.
So I have been thinking about doing this for a few weeks and finally getting around to it after trying to get the nitrates down though regular water changes etc. After thinking about it I decided to use the media tray area in my sump made it real easy. Where the red arrow is pointed.

So after taken the media tray out I put in some egg crate in its place, was added to support the screen which went on top of the egg crate like so. I purchased the screen at a craft store for 25 cents and cut it to fit the egg crate.

Next I need something to spread the water evenly over the screen. I had a piece of acrylic which I cut to match the bottom of the media tray including the hole pattern to spread the water over the screen.

Next I had to cut some "legs" to make sure this didn't rest on the screen (only a temp solution tell I get bracket made to hold this piece in place)

So here is the finally result of 30 min of work! Hopefully this helps with the nitrates starting off point is 50- ppm in the tank so we will see where it goes from here. Will also be making a cover to go over the back area where the light is and adding a second light to the set up. the cover will have slots to allow it to breath.

    These are very intriguing. One of my locals is doing the same thing, you can follow his progress at my local club site here: http://www.centralcoastreefkeepers.c...hp?f=24&t=1073
    It has been running for about a month and a half now.

    Interesting...so is the idea that the egg crate causes friction with the water and allows the algae to grow on the surfaces or how does this all work?

    Sedor- the screen "grows" algae all over it in time--few day to weeks. as the algae grows it use nitrates and phosphates in the water as food thus reducing the levels in my tank at least that is how works in theory. I forgot to note that I used sandpaper to rough up the screen so the algae sticks to it. Here is a link that I found http://forum.marinedepot.com/Topic89570-4-1.aspx kind of along the same line evoracer put up. Mt hope is that it helps reduce the nitrate battle in my tank!

    This sounds really interesting. Nice project.

    Awesome, I set one up a couple months back and it's definitly made a difference. I only get algae in the display on my rocks now. Once they've finished leaching phosphate that should go away too. Took mine about 6 weeks to really start growing well.

    Has anyone done a algae turf scrubers using LED lighting? If so anyone got pics?
    I'm thinking of doing a vertical screen with LED

    michika--thanks

    Alaska phil---good to hear that this has worked and made a difference....it will be great when it kicks in full steam

    angry monkey---I would think that it would work with LED lighting my bulbs I am running are 2 16W/ 5100k so as long it is along the same line I think it would work and save some $$ with the LED's
