Should i switch??

[pat]

Ok i've been reading about the advantages of running a bare bottom tank.
So my question is,i have an established sand bed that i would like to siphon out of my reef tank and go bare bottom.
Do you guys and girls see anything bad that could result from doing this?
I'm sure i can get it out by only siphoning 5 gallons(sand and water),I do 5 gallon a week change regardless.
I do have a stocked tank,sps,lps,clams ect...
Thanks
Pat

Hope this makes sense?????
