next juncture
pick where you get your procedural information from
you have opposing info, select the path you want. Advising that changing all the water is a nuclear path to someone that's conducted ten thousand full water changes on the oldest nano reef on the site seems immediately suspect advice, but it's your choice in how to proceed. everything about your tank is now checked against the predictions set above.
what I would do: as large of a water change as you can muster, and when pouring back the new water you don't let it smash into sand and create a cloud, pump it back in very slowly where the hose drains over rocks at the top, or into a heavy glass bowl that sits on the bottom as the tank fills. refill without sand clouding: that's your challenge
after the refill add some alternate reef life to gauge with, mantis could be impacted by poor salinity management, contams, things we'll never know as unstated variables so get some alternate life in the tank as the test. after the big water change with careful pour back.
I was also looking in pics to see if you had clams, tunicates, degrading and decaying things on the rock but those are clean and common macroalgae that are doing fine and nothing's at rot there. choose your procedure path at this point based off advices logged
