Ok, so hear goes, something i have been thinking about is letting 5 people with awsome tanks is using my roller filters in there systems for three months for free and see if it makes a difference in there tanks stability, water clarity, and maintainence overall better. You can use it for 3 months and at the end of the three months return it [ I''ll pay the shipping both ways ] or you can buy at the end, no strings attached. Just give your truthfull thoughts on what you see and overall does it make a difference. If you would like to try it all you have to do is post pics of your tank and sump on here and how you would install it. Good luck and looking forward to see some awsome setups,Ray.
