i have understood the book will not contain info describing construction since the beginning, i was getting it just to make sure i follow the guidelines and to answer some questions i have, and to cure some confusion on the subject. i am going to be using an ATS
on 2 tanks, one 55gal freshwater tank i have had up and running for 2yrs, to replace some of the filtration already present, and hopefully solve some water quality issues. the other tank is probably going to either be a 30gal or a 150gal tank reef tank. for the 2nd tank, i will most likely follow the dr adey's tray design.
the rotating drum design, in my mind deserves a chance, it might be 100% as efficient as the tray design, but it should generate respectable results and should be a good way to reduce the size requirements (compacting as much surface area into the smallest possible space) and possibly reduce the lighting requirements some (having to light only a small portion at a time, is the conclusion i have drawn).
the only downsides i see at the moment, are building a strong dependable drum ( i am thinking 6" pvc
if i can find it, or maybe 2drums @ 4" in diameter) its going to be taking a lot of abuse everyday and a suitable container to house the unit. for lighting i am thinking a 65w cv unit from homedepot should do the trick, but thats probably going to change after i thumb through the book. and the rotating drum is probably going to require a lot of fine tuning after completion. but this is all subject to change after i learn ins and outs from the book.
well when news of the ATS
reached me in 95-96 i was excited about this filter, but after finding the asking price of a commercial unit, the excitement faltered, till green started the discussion lately, so i am as much interested in the setup as you are ash, and have enjoyed participating in this thread so far. did you post a pic of your screens ? i have looked in the previous posts but didn't see any, and i wonder if missed them.
thanks again ash for your continual support.
