Are you talking about what is already in display?
I have an electric toothbrush that is actually meant for aquarium use, I may use that to hit spots of hair algae if ever needed, that's more so on a newer tank going through typical issues, rarely use it, but a regular toothbrush will work for that too.
Some do clean dietrus from live rock, siphon, point a powerhead or small pump maybe, or fan debris off, or even just having good flow can do that, just sometimes you may need to assist if there are dead spots and dietrus builds in areas.
Good to have 5g buckets dedicated to the tank, they don't need to be brand new, just free of solvents or anything harmful
