I'm confused. In January you said that your RO
unit was putting out .17ppm of PO4
and that you were running a PO4
reactor in your sump. In July it looks like you were changing lighting/bulbs. What did you end up with? Are you wet/dry w/ bioballs or LR
Looking at the Richmond Va water quality report, while it's not stellar it's certainly doesn't look that bad esp if you're running a 3 stage RO
w/ 2 DI
.85 is a pretty big number. when is the last time the unit was changed/flushed?
