    Nice!

    Technically, I don't think the outlet pipe really needs to be submerged, but it definitely needs to be lower than the "high" water level, and then it must be able to close off flow and become a full siphon. This might be achieved by putting a reducer on the outlet so that when flow starts, it seals off the pipe and then starts to purge the air from the pipe.

    Has anyone noticed an upsurge in interest for horizontal scrubbers since this statement a month ago?

    Pulsed flow

    Found this, and I'm a bit concerned

    http://www.enst.umd.edu/files/KangaD...ce Article.pdf

    According to the calculations from a single sided, pulsed flow system, these regularly produce 50grammes dry weight (2.5kgs wet weight) growth per square meter per day. Have done an approximation of my growth and it works out at 500grammes wet weight per square meter per day. I think you'll agree, I've got comparatively good growth compared to others. So why is its productivity so low compared to a single side horizontal? The only difference I see is laminar flow compared to pulsed flow. Thoughts please

    Well it certainly has piqued my interest. I think all of this forward progress made in the last 5 years or so warrants taking a step back and asking some fundamental questions. Plus, I'm going to order Dynamic Aquaria and read it finally.

    Right, got my pulsed flow set up working. Its a Horizontal and it'll soon have a couple of special features including a laminar flow baffle plate, special 3D screen and adjustable screen height platform,just for starters.
