I wanted to add some rocks to my aquarium. I went looking for rocks but had no luck. I found some at my pet store though for 35 cents a rock. They owner said they are base rocks and just rinse or boil the rocks and put them in the aquarium. I boiled the rocks for 30 minutes and put them in. The rocks made the water cloudy. Is there another way to treat the rocks to make the water less cloudy? I currently have them soaking in a 5 gal. bucket. Thanks.
