I'm trying to cycle some (20lbs or so) dead rock in a 15gallon tank. I put it in about two weeks ago, put on a powerhead, skimmer, heater, gac in a whisper and water from my display tank. I also introduced some squid to get things going and a chunk of filter material I had in the sump that I figure was already seeded.
Ammonia cycle is over, but the nitrites are through the roof and not coming down.
Q
o I do a water change anytime throughout the cycle or is the whole idea to make the LR a usable filter without water changes? How long does this typically take?
