Converting my 125g fresh/planted tank to a salt tank. The fresh tank was set up for around 3 years and I had used the red landscaping lava rock in the sump as a defuser. Question is, Can I just rinse this and use it in the salt sump? Should I be concerned about any negative leaching from the fresh tank or the rock itself (Its been in use for 3 years)?

If I wasn't so far over budget already (I should have known better :furious:) I would just buy some base rock and put it in there but if I can save a few bucks without risk I sure would like that.

Let me know what you guys think.

Thanks in advance.

I wouldn't, never know what kind of metals it will leach out.
