liquidg Posted May 11, 2014 Report Share Posted May 11, 2014 This little home made, 3 chamber reactor has smashed the additional phos that was always very high in the tubs down to zero, now all this is on one system. There is no such thing as zero but I am happy with nothing showing on a Salifert test and Danny’s Hanna tester, they are to expensive for me,lol.
