Cleaning crew question

[bsp]

I have a 12 gal nano. How many sand sifting cleaners should I use? Are sand sifting crabs a good idea? My tank has been set up for 10 months and doing well,but I think my sand should be cleaned,because I can't vaccum it. What are your thoughts?

to the left of this page there is a inverts options click it and click on the cleaner package ... click your tanks size and it should list what you need
