About 3 days ago I got my first tank, and after filling it with water it was cloudy. Thanks to the help from people on this board I realized this was normal and through filtering and adding AquaPlus it cleared up perfectly. Then yesterday I put my first fish into the tank (4 minnows) and everything seemed fine. I woke up this morning and the water is a little cloudy again (grayish, maybe whiteish), and it looks like it did when I but water in the tank the first day (maybe a little less now). What's going on? The fish seem happy, but the cloudiness concerns me a bit. Does it have anything to do with the fact I added fish to the water and their food (little gold fish flakes they're eating)?
