I built one and bought some pods to put in there. Hopefully the pods will stay in my frag tank. Also, since putting the acans in the frag tank, they look 10x better.
RIP Jerry. Came home today and found him dead. I guess the ride through the sump did him in. Or it could have been my wifes bastard cat that i found with his paw in the tank this morning. Either way i wont be trying one of these for a while.
