I'm starting a 75gal reef and want to establish a QT with a sponge filter. I have some fresh water tanks... can I "seed" a sponge filter in a fresh water tank, and then use it in my saltwater QT? Will the saltwater kill the freshwater nitrifying bacteria? Should I set up my 75 gal with LR/LS without fish and then use THAT tank to seed my sponge filter? OR get some LS or rubble from LFS for QT? Thanks.

Forget the sponge filter and use live rock and/or sand.

I can't answer the contamination between fresh and salt sponge use, but for a QT, I think it is generally not advised to use LR and sand for a variety of reasons. A sponge is really recommended, from all the expert advice I got when I had to qt my puffers. Nothing else in the tank like rock, sand, etc.. PM Puffer Queen and see if she has some advice for you.

Good luck!

i would just let your tank cycle and seed it for a couple days in there, if thats not the case maybe seed it behind the scenes at a LFS or a friends tank. i dont know about the freshwater thing though because i have never done it.

Freshwater bacteria will be killed in saltwater.

That would be my guess too.
