Okay so I started cycling my tank about two weeks ago with some slow growing plants and three guppies. At the end of that week I finally started seeing 0ppm ammonia and nitrite. Two days after I got three more guppies, initially only planned to get one male but saw females I really wanted so got them too. Now fastforward to like 4 days later and my ammonia just doesn't wanna go down. It's just staying at 0.25ppm or maybe less but not 0 and definitely not more. Last night I tested the water and got the same .25ppm ammonia, always 0 nitrites and about 5 or less ppm nitrates so I did a 50% water change but fell asleep before I could test the water again. This afternoon once I could I tested the water again and saw the same parameters so did pretty much another 50% water change. Two hours after I check again and the ammonia is still the same. This is the same color from the ammonia test I've been getting and I'm sure it's not a faulty kit because I tested my tap water for the water change after putting some conditioner in the water and it came out 0ppm. The first pic is the tap water parameters and the second is the tank's. I wanna know if I'm doing something wrong. I didn't feed my fish two days ago, gave them a sparse amount of bug bites yesterday right before the water change. Today gave them like one flake to share which disappeared in like 5 seconds. Their bellies are still plump so I know they're not dying starving and they seem fine, just constantly looking for food more than usual lol. I got some water sprite so maybe that will help with the issue? Or what do I need to do?
