Are the marineland perfecto's or whatever their called as good as oceanic. I know that the marinelands have a 20 year warrenty and have starfire glass as well. Do the oceanic's have lifetime warrenty? Which are better? I've seen some good prices on predrilled marineland perfectos at the petstore. One is a 150 gallon the other is a 300 gallon, which the 300 is well over double the price of the one fifty... any thoughts or comments are appricated... thx a bunch
