I'm restarting a tank after a 2 year break and want to avoid pests. I've bleached my old rock and equipment but have a 4 year old bag of unused dry Aragonite. Can I consider that substrate pest free at this point to rinse in RODI water and add to my cycle tank? Or should it still be sterilized in bleach/vinegar and thoroughly rinsed/dried first. (I've heard it's very difficult to remove all bleach from sand which will probably stall or kill my cycle). Thanks.
