Live rock along with cannister filter?

[JEP]

Hi,
When I originally set up my SW aquarium I was pretty much just interested with fish only. The guy at my LFS recommend then that I just buy a cannister filter and forego the live rock stating that I don't need both. But after spending a week reading numerous posts on this forum and looking at so many pictures that eveyone has posted I think I want to get some live rock of my own now and see what it "grows". The question is can I still use my cannister filter if I do get live rock because this is also my source of water flow? Will the mechanical filter cause a problem for the live rock inhabitants?
My aquarium specs:
- 46 G with 40 lbs. of argonite sand and 20 lbs. top layer of live argonite
sand
- Fluval 304 cannister filter system
- a small mountain of sterile decorative rocks
- 17W standard aquarium tube light at about 24 in. or so that the FS set me
up with
- 2 clowns, 1 damsel, 1 firefish

Thanks in advance

yea the live rock should be fine, but you will have to buy cured rock which can be pricy

Yeah, the canister wont harm, the live rock, and you can use both. Make sure to get cured rock, or cure your own by placing it in a seperate container for about a few weeks.

Oh, and by seperate container I mean another aquarium or something that can hold it. Put some fresh saltwater in there an a small powerhead.
