I agreed with you . When my friend told me that he has successfully extracted special bacteria strain from Mangroves. I took it with a grain of salt . Now when I saw what it did to my tank , I am now trying to make him produce more and go commercial so we can all benefit . Lets see what I can do as he is a scientist type of person , only want to win trophies not moneyJust mad...i m looking forward to get that bacteria strain too. Such a clean sump.
