Adding New Rocks Question

reefer0708 · May 5, 2019

Im redoing half of my DT.
Got this pile of dried rocks last night.
Was told that they've been sitting outside for 4 months.
Should I bleach these 1st for a week...or should I start curing right away?
Is curing even necessary for adding new dried rocks to an established tank?

Thanks in advance [emoji120]

If you're 100% sure they haven't been exposed to any toxins it's fine to rinse them well to get any dead organisms off and add them to the tank. You shouldn't add them all at once but over a period of several weeks because any decaying organisms left behind could cause an ammonia spike if too much is added at once
