thank youThey might have covered it somewhere else, but this one jumps to mind:
How Did the BRS160 Survive Our Mistakes?! Lessons Learned from Our Failures.
Learn from our mistakes so you don't have to make those same mistakes on your own tank! In Part II of the BRS160 update, Randy and Ryan walk you through some of the serious mistakes we made over the last 5 years. We cover a variety of topics ranging from internal water flow and removing
yes I have heard of that

I always siphon my sand bed because of the detritus build up, the siphoned sand water is black and smells like rotten eggs. I do it very carefully and I have never changed my sandbed, I have added a gallon or so of sand but never changed it. My corals get a little slimy ;/ but they don’t ever die or get bacterial infection or tissue necrosis. I raise a lot of cheato that removes nitrates and phosphates in the water column but curious if changing it is due to lack of maintenance or if the sand really goes bad?
That’s a pretty tank!!!Many people change a section of their sand bed out regularly i myself change nearly 100% of my sand bed in my nano every 3 months and in my previous larger reef before that i changed about 30% every 3 to 4 months and have done so for the past 18 years and see nothing but positive results from the method, it is an excellent export and refreshing mechanism helping towards preventing old tank syndrome
On a sand bed that is deeper or sat for a long time a VERY cautious approach is required as a lot of nasties will potentially have built up that you don't really want to disturb into the water column which is one of the reasons why deep sand beds fell out of favour and are often referred to as ticking time bombs, despite what many believe they do have a finite lifespan even with maintenance and will at some point require intervention/refreshing or at some point it will reach critical mass as it were
Personally i advise people determined to run a DSB to run it in the sump in two separate tubs that way every 3 years a tub can be pulled and replaced with fresh sand so in that way it never reaches critical mass and can be run indefinitely on this rotation method and doesn't become problematic
BRS had issues because they unbalanced the system by trying to remove and not replace and go bare bottom that is one of the reasons they are very much pro sand bed now
Here is my nano that i suck the used smelly discoloured sand out with a hose and replace with glorious bright white sand every 3 months
And i use this tube with half a pop bottle to put the sand in right to the bottom exactly where i want it to go with no mess

Geezs every 3 months thats what i call dedication . i eill try and remove little by little it will be interesting .Many people change a section of their sand bed out regularly i myself change nearly 100% of my sand bed in my nano every 3 months and in my previous larger reef before that i changed about 30% every 3 to 4 months and have done so for the past 18 years and see nothing but positive results from the method, it is an excellent export and refreshing mechanism helping towards preventing old tank syndrome

I second this. While BRS had problems, you'll find supporting evidence from @brandon429 that suggest it can easily be done. I use his experience and advice to change sand in a small tank without issue.
