When switching from FW, can I reuse my gravel and rocks?

[runway1]

I'm switching from a fw tank to a sw tank. Can I reuse my lava rock and coarse gravel? Also, do I need to clean/replace my bio balls?

Thanks all.

Lava rock doesn't respond as well as some other rocks to coraline algae. I wouldn't use coarse gravel in a saltwater aquarium as it isn't good for various species that live in or on top of the substrate. What would you be using the bio-balls for? Are you thinking of setting up a sump?

I have a wet/dry with bio balls. Are they appropriate for saltwater? Do I need to clean them before reuse?

I would clean the wet/dry and replace all of the filter pads with new ones. You can use the bioballs for SW but it is a better option to get ride of them and replace them LR or LR rubble instead. It is a much better filter media for SW.

You can se your freshwater stuff for salt water my pizza place has one...but it doesnt have any coralline growth in it as someone stated earlier.
