Okay so I have been cycling my tank. I am doing various mini cycles until I’m able to get from 2ppm to 0 in 24 hours. This was going good and I was almost finished until I decided to do a water change and noticed my ammonia spiking to .4 ppm after that . I tested my water and I’m reading .4 ammonia. I decided to then purchase a new DI Resin believing maybe I have wasted through it. I replaced the filter and yet I’m still getting the same readings? Help!!!!!!!!! P.S I’m getting 0 TDS
