Has a concensus ever been reached about the cause of "old tank syndrome" or are there still just a lot of best guesses? I was thinking about my next and last system (as I often do) and OTS popped into my head as being something I needed to plan around. I was thinking it's caused by a failure to replace the sand bed every couple years but I wasn't entirely sure.
