I'm linking this thread to the sand rinse thread ironically not because of a sandbed, but as a review of natural and expected detritus production.
You have no sandbed, so you're forced to clean daily to maintain -that scape-
And in the frustration you reveal the work required to maintain real estate, to prevent clogging of pores, stagnation, pockets of algae feed, the work you feel might be a harbinger is really just the key to an infinite lifespan no old tank syndrome reef.
This isn't stated in order to start an approach battle on clean vs detritus storage/sinking into the bed which is 'out of sight, out of mind'
It's stated because you've chosen to assemble a low detritus reef that people who are reading want. Those live rocks are apartment complexes for poopers lol you are making up for the fact an aquarium doesn't have the current nor the export to match the ocean, this cleaning isn't bad, it's a sign of a person not willing to lose an awesome scape to some scum invader mat or plant...by letting it sit, awaiting twenty days for a microscope + ID thread + random prescription for N and P levels as it takes over the whole tank
No, you are willing the surfaces clean routinely, we can see, even if you didn't describe it. Live rock from anyone's tank, if set in a white paint bucket for two hours, leaves detritus pellets behind
Sandbedders sink it, claim it to be mineralized eventually, and constitute every entrant into our tank saving threads.
And then other tanks just simply never let the invasion cycle and alternating species of invasions begin, they're as clean as they need to be to force substrate (your rock) compliance
What's very possibly going on with your tank is that it's cycling through a small Invader every time we add corals from another system these things vector in
You can use better mechanical filtration to catch these particles inside of filter floss that is exported in cleaned or you can continue holding course either way your system is working great it's not in distress
This is the reason I only work with pico reefs, am not willing to expend the effort to correctly run a large tank with certainty... you are. It's the only way I know to reef that has 100% consistent outcome for attempts, at the expense of work though. I'm jealous of the lucky ones, hands off reefers who can age tanks that way but those approaches are also the sole entrants into our tank correction threads. The clean reefers apply the fix before hand, as a routine.
