That's the plan with my water changes, shut off the return pump, heaters, etc. Drain the sump, vacuum it and wipe down. Fill up with new salt water... BAM! Water change and sump cleaning all at once in 20 minutes. I hate detritus in a sump!
Turkey baster for spot feeding and blasting rock. $1 store plastic mixing bowl and pasta strainer for dipping corals. Super glue gel for glueing corals. Electrical conduit for mounting lights. Razor blades for scraping, fragging, cutting ect.
So I grab hers and use them as frozen food strainer, as a carbon mesh in the sump, or with any crazy idea I could came up that needs some kind fine filtration.
