Recently visited my favorite LFS. Apparently a RIO pump casing cracked and fried the clam lagoon (big clam only shallow display). Wow! Very very sad. This guy lost 12 very large Derasa's and MAximas. I WILL NEVER BUY A RIO PUMP. They are cheap shoddy poorly built pieces of #@$$.

I have used Miracle Mud for almost a year now. The calurpa is very fast growing. I have a 55 gallon reef and a 20 gallon sump partitioned with 10 lbs of MM. I also mixed 20 lbs of aragonite sugar sand into the mud. I remove half the algae on a monthly basis. I think the iron helps the calurpa...
