From what I have been able to find on other forums, this stuff has been successful in the past.
Now, the question is the %. Most references I found said that it's 5% ammonia. Does the bottle/company have a number to call & double check this? If not, put the numbers into the calculator to figure out the ml dose. Then only add 1/2 the dose. Wait atleast 15mins (with your filter on) and check your ammonia level. If its truly 5%, it should read @2ppm. Then go ahead & add the other 1/2 the dose. Remember to adjust the 'ppm
' on the calculator from the default # (5ppm) to 4ppm.
