    Hmmm... I wonder if....?

    Oh forget it.

    Does nobody conclude that the "thicker" growth is acting as a particle filter ? When I grew my screen thin i.e. 7 or 8 days, the water contained within the mat was a dirty brown green, full of detrital particles. This situation changes, the longer the screen is left between cleaning. At 14 to 28 days, the water within the mat is crystal clear. This presumably means the detrital particles have been consumed by bacteria. However, there's a problem with this theory. In my G.H.O.S.T. Screen, the detrital particles settle quickly because its horizontal and seem to remain there for an extended period of time without significant breakdown. There is a difference between the algae growth however. The detritus on the waterfall screen is in direct contact with the algae (and bacterial assemblages), whereas the ditritus collected on the G.H.O.S.T. is away from most of the algae mass (which tends to accumulate near the surface) and the water passes under the algae mat.

    Yes, noticed that. The longer you let it grow the more crap gets stuck in it too.

    I noticed the detritus also, but if I wanted a detritus trap I would simply use a filter sock. ;) I just want the algae to work better than what I have experienced on my waterfall systems as I feel there has to be a much better method to achieve that, and why I have such high hopes the surge method is the answer. It may not turn out to be, but to me it seems like the best bet to date to achieve maximum filtration via algae.

    So according to your experience, what would be the correct guide for the mesh size and the number of LED

    Well for LED IMO nothing has changed. one deep red LED on each side of every 4 to 8 square inches of material.
