I run with a half crushed coral and half sandbed setup with both being about 3/4 of an inch deep I don't bother vacuuming that's why I got snails, shrimp, cucumbers and such they do the work for me. I just do a water change

First I drain 10 gallons out of my quarantine tank, and dump it down the toilet. I run my display tank bare bottom. I stir up the detritus with my hand then I suck out 10 gallons from the display tank. I let the detritus settle in the buckets , then I pour off the water into my quarantine tank. I do this once a week.
