DSB Cleaning

[Scales]

There are currently a couple of long threads on RC dealing with these issues. Not being computer proficient, I am unable to provide a quick link. I recall one being labelled "DSB Heresy" or something of that nature. There is much discussion about the "standard" DSB theory, which is often attacked. Some propose modification to accepted DSB "practice", including the management of anaerobic/anoxic zones within a sand bed. There is also discussion of phosphate binding.

Interesting for both its content and the heated discussions/personal attacks among the proponents of conflicting theories.

Cheers.
