thedaikon Posted October 10, 2017 Report Share Posted October 10, 2017 Do you guys remineralize your RODI water when doing a fishless cycle? I'm asking cause I have been stuck at .25-.50 ammonia for about 3 weeks now. Nitrates have been going up and nitrites have been at zero. I've tried everything from 30% 50% 90% water changes to reseeding with a second bottle of tetra safestart but the ammonia remains constant. PH is at 6.5 and temperature is at 72 degrees. No idea what I can do now and hoping for you all's help. Thanks! Quote Link to comment Share on other sites More sharing options...
