Ocean rock that is!!! I am in ct and I picked up some ocean rock/ dead coral rock for my AC tank. They only had 20 lbs and they usually don't carry it. Where can I get more? Or should I just go with tufa for the rest? I would like to get another 20 to 50lbs worth for my 125 gallon tank. I was suprised that they had any and it was reaaly the only time I have seen it available anywhere around here
