fast cycle.

[spikehs]

Hey all,

It's 1 week since i set up the new tank, I tested ammonia and nitrite every day never to really see an increase in either. I tested today for nitrate and noticed it was at ~5ppm. Can a tank with adequate LR cycle this fast? I have set up a few tanks before but never properly
the tank is 50gal, with 33gal sump (only about half full) with ~80 pounds of LR. Seems a little quick to cycle to me....
