hi, just curious, tank has been running for almost a year, crashed recently pretty bad, let it cycle for about 2 weeks, all levels were fine. i changed from bio balls in sump to live rock. for the last 3 days, my nitrates are at a standstill at 20 ppms. should i worry? could it be from the fish i recently added or the cured live rock i added to sump or possibly the coral? thanks for any inside advice. new to this forum, before i use to take different advice from different saltwater shop employees, which don't really help being they all have there own opinion thanks again
