Cathie Jenkins - 08/31/2008  For reviewer who is unable to test whether this is working: this is easily done - buy yourself an aquarium nitrate test kit (e.g. made by API) which costs about £7 - test your tap water from unfiltered tap, then test your tap water from tap attached to your water filter.
I find it reduces my nitrate levels from about 40 ppm to less than 10 ppm. |
Brian Perry - 06/27/2008  I am unable to test that the filter is working correctly, I am trusting the supplier that this filter works correctly. |
