I tested my water levels last night and I was showing a small amount of amonia, less than .25 and my Nitrates were over 40. I am 99.9% sure this is due to me overfeeding. When I get hometoday I am goingot do a 25% water change, hit the gravel with the vac to try and get the levels back down to normal. I think the reason I over feed is a lot of the food sinks to the bottom so half my fish lets say, dont get any. I am not sure why it just hit me, but I thought about turning my filter and air stones off during feeding time. Is that ok?
