Yeah u can get dry rocks from bulkreefsupply. Once u get them, remove any thing that's no supposed to be there. Soak in saltwater for a month with powerhead. And wait and measure. It should be ok once ammonia is zero. Po4 is zero. If u want to cycle, add microbacter7. Cycle complete when nitrate is zero. Once done change water and wait a fee days and measure again. Patience. Good luck!
