That would be the next thing to check, yes. Low pH or temp could inhibit the cycling process. 17 days is an untypically long time for ammonia not to have dropped even without seeding.60gallon said:Just curious whats your temp and PH at?
That's correct. You shouldn't add more ammonia until it drops to 0. At that time, you'll see nitrite spiking.Didnt think to add more until its drops and the nitrate spikes.
