I have been able to keep the activated charcoal working by gently crushing the larger chunks to expose additional surface area. I suppose it could stop working at some point but I just keep adding fresh and it keeps on working. I did have a problem when I tried putting it in nylon stockings. I removed it when it was not doing it's thing after a week and discovered the AC was dry! Guess I will use cotton bags or the pond planting pots with the perforated sides as I have done before. I am surprised you could not find the AC at Lowes. They always have it here in the house plant department. Sandy

you can always just save the pdf file to your pc then open it with xchange.

Have you tried changing your Internet Explorer settings to accept the Active X control? Tools, Internet Options, Security, Custom Level... If you're using another browser check to see if there's a way to accept that particular Active X control. Rita

nonnie_ga even if you do get your IE work properly it is a very good idea to get firefox as a second browser because if you do not have an alternative browser on the pc and IE fails then you have no way to get on the internet so to have at the least 2 browsers is preferred and you can have more than that, you could try Opera and the Google Chrome browser also but firefox is very easy to download set up and use, you can have it install all your IE favorites at the time you install it then you have them on both. You do not have to choose to set it as default you can leave your IE as default, simply click on the firefox icon when you need to use it. You can actually have both IE and firefox running at the same time also. Try Firefox should you need help with it just ask, I love firefox and use it daily and have a lot of very helpful add ons.
