I was recently reading aquarium fish international magazine and saw an ad for a new product given out by hydor. It is called "MAGI-KLEAN". Basically it removes calcium and lime deposits on your aquarium supplies. They will send you a free sample, asking you will provide feed back on how you liked it. I think it would be a great opprotunity to try out a new product (that hopefully works...). Here is the link to get the free sample http://www.hydor.com/magiklean/contact.php .
Best wishes!
