Sentinel claim X-900 works and get rid of all crud which is caught by the filter. Has anyone used this stuff to report back?
But in your earlier post you wrote that X900 would do....
Now you are asking if anyone has used it.
You are demonstrating that you are only an armchair expert who has no practical experience!
If you are merely quote a manufacturer's claims ( which may be false and are almost certain to be over stating what it will do in practice ) then you should make that clear!
