our sand rinse thread is page after page of takedown cleanings with anything in tow, no arrangement in a nano is hard to work with. so many creative options, such as while you are rinsing off the rocks externally in the sink with saltwater, the anem is getting mist sprayed to keep it wet by someone else, giving you out of water work time
the sandbed, right now if you reach and grab sand and drop any, I bet a giant cloud erupts. if not, then no need to rinse sand at all, if it does, you should, that's invader feed and invader itself depending on what more detailed pics would show (white light, clearer standing back ones too)
*not everyone agrees with sandbed rinsing, that's what the tank cleaners do. dosers and param tuners leave all the sandbed accumulation in place and work through the water only. you'll have to choose your method as you see fit.
here's our thread for you to see cleaning galore by all size tanks, they're moving and upgrading etc so they had to make the changes, its no different if you are choosing to employ them to rid an invader.
most will not use the hand cleaning as stated above, that's last resort after they start to lose things or even for the next tank. People tend to hold onto their invasions, tightly.
we never ID any invader in this thread, nor take param measures for the tanks because they are forms of hesitation. we go off the assumption that an invader is caused by you purposefully farming it, when a kill option existed. ID is for people who must work through the water only, so that you can match a chemical or a param to a known invader.
we are anti hesitation there, all the way
no time to id

that will at least show you the order of takedown, the work involved and if you want to make it custom for yours we can.
no harm in experimenting with additions or subtractions of things, our method can be ran at anytime even as catchup. in that thread, we think an invader that shows up isn't a surprise, we're importing too many microbes to enumerate
anything can show
what is a surprise is an organism that keeps a footing on vital space after three rip cleans, which we never see, cuz it takes act of reef congress to sell even only one rip clean
the absolutely fed up don't have to be sold, they post up saying lets rip this thing apart Im angry. and we do. its fine if you want to experiment with additions, heck with today's retail options for sludge digesting and competing strains of bacteria Im not surprised if one of them wins out, but that's lucking.
we'd have it rip cleaned and under compliance by end of week no questions asked, all work done by you. sometimes a repeat is needed depending on variables like depth of cleaning and mass accumulation/deposits in the rocks etc. to be able to part clean any tank without killing it is the benefit.
