Ugh...not sure what the cycle is doing. Nitrite spiked over a week ago and then settled down around .25 ppm with help of a water change. Got that reading for a few days, had absolutely no sign of ammonia...did a water change Saturday and figured I'd give it sometime to see where it settles out and then dose ammonia again to see how quick it gets processed.
Well tonight I tested. 2 ppm NH3 and 5+ ppm NO2. :wall:
No idea where this is coming from. Haven't dosed any ammonia since the nitrite spiked initially, so well over a week ago. There's nothing but plants and snails, which could be contributing to ammonia (plant decomp, etc.) however I have no idea why it decided to spike now and how it got this high since I did a 50% wc only three days ago. Didn't touch anything other than picking up some mulm from the substrate, actually removed dieing plant matter, and moved the rock off the wood onto the substrate (nothing significant was kicked up as far as I could tell).
Trace amounts I could explain, but this is rather significant to pop up seemingly overnight.
