My tank was dying fast,pronounced leaking around the lid and effluent starting to pond, not to mention the smell.I was the biggest skeptic,so buying an internet product for such a serious problem was really hard to do,but I'm glad I did! The remediator is nothing short of a miracle. You'll be astounded at the results. Don't let the pump companys told you there's no hope except expensive repairs. Install the sytem(easy to do) and you'll have peace of mind while saving a large chunk of money. Thanks Karl and crew for your great support and outstanding product!
