if you did not remove that stuff, and it compiled, how much would you allow it to build up before removing> it seems it must be removed in some way, nothing in the tank removes the detritus
vs partial removals, what about just rip cleaning the whole sandbed to total perfection like I did below
then add all the stuff back. stays clean months, and no cloud, by doing it all at once vs partials.
as soon as dinos or cyano or other invasions like GHA set in, they feed off that cloud. you will find it very rare that a nano reef doesnt cloud when the bed is disturbed like that above...even when seemingly kept clean/reach in and grab some/if it clouds anyway, animals are just cleaning top layers only and that food/waste material is compounding.
a clean bed can pass a disturbance test. The reason people are going bare bottom nowadays has to do with what you are seeing. the clouding you see is a bell curve, and nothing is wrong with it until downslope time, and that time varies setting to setting and tank to tank. usually within 24 mos of total hands off on your sized nano.
that vase is now 14 yrs old/same corals due to constantly intercepting the bell curve at the good part heh. timing did it
