Johnny Fingers I've done a full system flush. I washed and went through threw the buckets with hundreds of gallons. How can you feed a hydo system @ 7.0 if there uptake will be so diminished?
I've been setting my Rez @ 4.3 and fist pail is 5.8 last pail is 6.7. PH down is used everyday. I feed them GH 3 Part system with hydrozyme Cal-Mag and Foil With VHO. I [plan on hitting them with some Flora Nova later on. Straight TAP 7.8.


Is that enought?
