filtration salt tank or the lack there of...

[inari]

If you guys have seen the other post that I have. I'm wanting to set up a Crabatate tank for some land hermits. I'm wondering what filtration unit has the weakest current. I'm looking for something that will allow me have very extremely small inverts. When Land hermit crabs are born they live a time in salt water...like the ocean (just in case someone is haveing an off day) I want something that will not suck them up and kill them but at the same time I want something that will filter out the poisons in the water. Any help is much appreciated. I still have not tried it. If you want the other post you should be able to search by my most recent posts and threads

Did you ever find one? Did you ever start your set up? What do you have? Have they bred?
