If it is a SALTWATER tank, then no....you need more specalized rocks.
If it is a FRESHWATER tank.....then yes...you can use rocks from the outdoors. HOWEVER.......you need to make sure they are very clean. My suggestion to you would be to (and this is going to sound funny)....but put them in the dishwasher (if they are BIG enough to stay on the rack during the wash cycle. Once they come out of the dishwasher, rinse, rinse, rinse them.....and when you think you FOR SURE have all the soap off of them.....rinse them one more time...just to make sure you do!!!
Hope this helps! |
