Ok... I have massive pearling (finally), at least very good pearling, but all my fish are listless and lathargic *during* the peak pearling hours. My PH is below my high range test kit, but I would guess the ph is about 5.8 based on it is about 2 grades of yellow below the 6.2 on the test strip.
Evidence of pearling - lotus plants, so many bubble some leaves *flute* up.
What do I do? I thought that I would have massive O2 under these conditions. Is it the PH drop?
120gal, 390watts, 6 to 8 bubbles per second pressurized C02 into home made reactor, EI ferts. 2 days after a 50/50 water change.
