I guess I should ask how old your system is. It may have been previously stated but I forget by now.

Much of the rock is 4 years old, the seed rock (about 5 pounds is about 6 years old). the rest (about 30 percent) is about 1 year old. The tank itelf (sump included) is about 5 months old but EVERYTHING was transfered from the old tank....so on average.....3 years old.

Some of the corals are 8 years old. Been through 5 transfers!
