Salex, beware! The youngest of my certified triploid GC are now 22 yrs. old! I estimate that I still have about 20 of them (I'll have to wait until the ice melts to make a 2011 estimate). I'm aware of the science that asserts triploids will live only 10-15 yrs., but my own anecdotal evidence says otherwise. Here is a photo of my water in August. Before the GC it used to be three times clearer, albiet much weedier. I wish I had never stocked them.
