If you know of anyone who has an established tank ask to steal some of their gravel and hang in the tank in a filter bag....that will help speed things up quite a bit. I once used a biowheel from an existing tank for a new tank and never saw a spike in either tank! When a Q tank spiked only nitrites for 2 days after medications, water changes didn't bring it down quick enough for my happiness I put some gravel from another tank in, and the next day levels were back to 0. You need good bacteria to counteract the bad (fish and food waste)
