gravel from garden supply store?
i bought a huge bag of large landscaping decorative rocks/gravel from my local garden/hardware store. i think its a 40 lb bag, and for 5.99 i thought it would be good to use in my new aquarium set up. the rocks are natural not dyed and are about 1 inch in size, but they were quite sandy. i rinsed and rinsed until the water was clear but when i added it to the aquarium and i filled it with water i noticed a slight cloud still coming from the gravel. the filter has cleared it some after a few hours but im wondering now if this is safe for the fish? did i do a boo boo?
