hi you seem to be comparing the tt with the tricle filter, if you are. you are right about it being more eficiant i would not go as far as saying 100 times, but one third of media volume which would probably give you a filter quarter the size of a submerged filter, a higher stocking level and higher pumping capasity, no dwelltime,?

the tt and the t filter are totally differant. haveing said that if you could combine the two you would have a perfect fillter?
i too am very interested in this thread nobody seems to know why it works , i personally like doc conrads theiry about bacteria converting the nitrate to gas then being expelled into the atmosphere, if not the gas gets reabsorbed into the water and back into the pond as nitrate, shuerly a simple test for this would be to get a tt that is known to work and encase it so that the gas cant escape if this is why the tt works the nitrate would increase and you have your answer, if this is the case the tt would be more easally adaptobal to differant situations, the more we know the more we can use to are advantage. i have noticed that bio balls seem to be the prefered media virtually unclogable and very open which leans me towards the theary about the gas exchange, also the slower the trickle the better if there was lots of water splashin about comeing in contact with the gas reabsorbing the nitrate,
thats just my opinion the only knowledge i have on the tt is by this very interesting thread
