not everyone has a sump why dont you get a group buy togher and ask someone in the UK to ship a load over to you
i get pellets shipped over from Li all the time
im sure i chould sort something out we should be able to send say 20-50 over then you have no excuse not to have them on your heaters
everyone thinks its not going to happen to them the bang their rays get burnt
when i 1st started out with rays it happened to me so it can happen to anyone who doesnt have a gaurd on their heater no matter how safe you think you are no matter how you have your heater if they are in the tank then their is a risk
