I started a 10 gallon tank for 2 bettas. We divided the tank in half so they cant fight, and we have enough decorations so they can swim easily, yet can hide if they need too. Everything is new except the tank, we rinsed everything and its been running great but today it was a little cloudy. We checked the filter, its fine, and i skimmed some little specks of dust of the top. We were planning on getting the fish tomorrow but we want to know how long we should let it run for now or what we can use to clear the tank.
