I have been using two diy bottles utilizing the jello mix formula for just over 24 hrs. I am getting some bubbles from each bottle but I am not sure how many it should be generating. I did a complete test of everything just before I introduced the co2 into the tank and now more than 24 hrs later my tank readings are exactly the same. I had expected the ph to drop or maybe the kh but no, everything has remained the same. My question is, since I live at approx 9500 ft. will I need to adjust the formula for my generators? :huh:
