i recieved some free live rock from a fellow Aquarian. her tnk crashed from calurpa going sexual after a power outage. any ways, it had a ton of bristle worms on it. it sat out in the air for about 5 hours, it does have calurpa on it but im slowly removing it, it has been cycled for a week now it inly went to .25 ppm ammonia but it never registered nitrites natrates are at 10 ppm not with 0 ammonia and nitrites,, i havent been able to catch any worms. are they dead? some had red outlines to which i think were fireworms but not sure. i havent seen any since the first day i recieved them. is it safe to use now? thanks for any advice. also i used stability to help with the cycle if that helps or not.
