Absolutely! It also requires, as I've pointed out several times throughout the thread, the maintainance of a fully functioning sandbed and full compliment of the macro and microfauna required to keep it functioning. It is in no way, shape, or form a simple create it and forget it methodology. In many ways, it is probably just as time intensive as yours, but is in my opinion just a more natural way of accomplishing the same result. You might get some purists who would want to argue that, but I'm not one. I believe is using whatever methods are time proven by you to work for you. For myself, I've found this to be a large combination of methods. I've even used the siphon on occassions, just not on a regular basis .
In regards to the comment on DSB failure do to improper set-up, I've found that many people in establishing a DSB don't bother to research or learn enough in regards to the proper way to set one up. They simply hear about this idea, go out and buy a bunch of the same-sized sand and dump it into the tank to the desired tank and then expect it to function. A properly set-up DSB requires three layers of sand grains of different sizes, with the most course or plenum being on the bottom, the medium in the middle and the fine on top. While there is some evidence that similar-sized sandgrains may work, to my knowledge its never been researched like the original method (albiet in a somewhat biased manner). Additionally many people never really bother to learn about proper depth, they place sand to a depth that looks nice to them. Few are aware that the depth of 2" to 3 1/2" for example are extremely high risk, as they are neither deep enough for a true DSB or shallow enough for a SSB. Risk of accumulation and release of toxic gases in these sandbeds is much higher than in a properly established DSB. Its a unfortunate case of failure before the system ever started. Then people blame the crash on the DSB, in reality its a failure of the individual rather than the method.
Very well put. Im sure everyone who has read this learned something valuable to apply to their own systems. I should have named this thread "Maintain your sand bed!" lol.
