G geno Member Market Messages 443 Reaction score 0 Apr 1, 2009 #1 I installed new 14K Phoenix bulbs (3x150) and noticed that my pH reading is now lower that it was when I had the old 10K bulbs. (8.05 vs. 8.22) Is this just coincidence or should I expect some variation due to lighting? thanks, -gene
