Oh no!!! I really hope he's still around. Is he maybe still in business just not here? I can try to track down an email addy for you if that would help?
I feel sorry for you if that's not a typo..... 509 lbs? Either way if Charlie isn't around I'm not sure where would be the next best place to get them.... Charlie was crazy cheap!
Back to the topic..... Friendly advice, I'm not sure I'd rely strickly on submerged media if you have hard water. Deposits can wipe out the surface area of stuff like rings. Personally, I'd go wet dry before submerged, but then again if I had really soft water maybe it would be different, but the increased oxygenation of using a wet/dry isn't debatable.
