Thanks for you help guys

IMO I perfer to purchase all my rock as 'live rock' instead of waiting to seed dead rock. IMO its worth the higher price to have as much life as possible introduced to your system in the form or algaes, polyps, animals ect. I dont know how long it would take to fully seed dead rock but I can only guess it would take a long time before it can be compared to purchased LR.
