| | What do PH fluctuations mean?
I have 4 tanks, from 4 months to over two years old. They have been low-light, low tech, just flourite and good wishes. One month ago I upgraded the lighting on two, and doubled up the old lights on the other two. I have two on DIY yeast set-ups, one which works and the other is inconsistent. I have been checking the PH morning and night for the last few weeks, and the 20 gallon that I put 48w of T5 on fluctuates from about 7.2 in the morning to 8.0 at dinnertime, every day. It is the one with the sputtering DIY system, that hits 4 BPM on a good day. All of the others sit steady at about 7.4 all the time. Two others are higher WPG, including the one with working CO2. Everything seems fine with the 20 gal, the adult algae eater has grown over 1/2" this month! The anubias look like green velvet. I guess I am just wondering if something is going right, or if something is lacking.
