just a question how do you remove the detritus from the system...on a weekly basis I low all my rock work and crevices clean what is the point then of blowing it around and keeping it in suspension just to have it collect somewhere else I want it removed from my system....... again just a question we work so hard to keep our systems clean why not remove whatever we can to me its a small expense compared to trying to control the consequences of detritus build up. Less detritus means less nutrient sources which will help keep things like algae out of your tank.
again not saying you are wrong just asking a question is all
I've never really been that concerned with removing detritus completely from my system.
At the end of the day what we want is proper parameters for no3 and po4 and not large amounts of algae building up which is likely due mostly to high po4 or silicate. I've never had to run any kind of mesh filtration in order to achieve these results and I know many other successful reefers who do not either. Ive always blown off my rocks in DT and crank the flow in my frag tang to stir everything up and get some water movement into where normally there isn't any. But I've never been concerned with actually trying to remove any of the particles. I've always believed and has success with the mentality to keep stable water parameters and let the water do it's job. This would require of course getting the detritus stirred into the water column rather than just letting it sit in an area with very little to no water movement for extended periods of time.
People are always concerned with boiling rock or acid bath too to eliminate the phosphate or whatever else may be trapped within. The best method to eliminate these ions is still to put it into circulating water with proper parameters and let it leach out.
