hi all, started my 180 off again 2 weeks ago. stuck a clam on top of the trickle tower for 3 days to get the cycle started. after 1 week no2 went up to 0.3mg/l took a reading just now and its nearly back to 0. has it cycled ? or didnt i leave the clam there long enough ? sorry for the dumb Q, its been a long time since i cycled a tank.
