LB, when the ammonia hits zero dose to 2ppm not 4 or 5. This will reduce the severity of the nitrite production giving the N-bacs a chance to catch up. So glad you're seeing some progress
Just wanted to update this thread to say that as of tonight I have double zeros!!!!
I'm still not sure what the problem was, but after changing over to spring water and adding another seeded filter my cycle took off. Had nitrites the next day which rose to 5 and stayed there for a couple of weeks then started to come down a few days ago and tonight it's back to 0. I need to fix some things on the tank first (need a new stand, finish filling in the silk plants, fix the background which is coming off for some reason), so that will give me a week or so to keep testing the cycle to make sure it's secure before I start adding fish. I'm going to update my initial log thread also just for future reference for anyone who might read this in the future, then I'll post about stocking advice.
