Its my opinion we've (hobby) have established a very strong link between detritus either packed in sand or in rock pores as the supporting #1 substrate to fuel invasive cyano, this cleaning directly lowers your risk of cyano as your rocks and corals continue to age I'd testify to a reef grand jury.
I would testify in a reef court of law you just did the #1 thing required to stop/prevent and reverse old tank syndrome in reefing. What you did is the key to an infinite biological lifespan reef, extremely old micromodels indicate ~ either make a throughput system that doesnt store, or enjoy the looks zonation and benefit of storage zones (sand) but mimic a storm event every so often and blast that stuff out = infinite biological lifespan not having to buy anything from a retail store or pay for a tank measure.
if you do this off and on for good, the reef lives until a hardware issue kills it.
You intervened in old tank syndrome before it happened, is there any other better time
as soon as we get a cloudless re assemble Ill make this #1 read for sure in sr thread
