    Cycling question all levels are high after change

    I have a question that I hope someone can answer. I have been cycling my tank fishless for 5 weeks. I have 75 gallon tank using dry rock 90 pounds and live sand 120 lbs. Using a fluval Fx6 canister filter. Also In the tank is 2 powerheads and a HOB skimmer that both seem to be working well...

    Nitrite problem

    I want to say my tank is stuck in the nitrite phase of the cycle. The nitrites have been off the charts for about 3 weeks now. Should I do a water change or let the tank establish more bacteria and process the nitrites?
