tank has been up for about 2 weeks now, bought 25 ponds of live rock, added 20 lbs. of live sand, and added a raw shrimp to add even more bacteria for cycle. as you can see the live rock has plenty of life of it. One question on the pics, to the lower left you can see what i am assuming is a cucumber..are these dangerous if they were to die, pollute the water.. I found a couple more on the rocks growing as well as the dreaded Aptasia...can not wait for cycle to complete
