Hey guys. I was hoping you could help me with some understanding regarding a few comments by Takashi Amano in his book "Nature Aquarium World" Book 1.
Pg. 174
"To find out how much CO2 the plants are consuming, compare the pH levels of the morning and the evening. The pH should be at its lowest level in the morning (before turning on the light) after a night of fishes respirating oxygen and expiring CO2, and at its highest level in the evening (before lights out) after a day of plant absorption of CO2 and discharge of oxygen. The greater the difference between these two values, the greater the consumption of CO2, and therefore the greater the health of the plants."
Question 1: What are your thoughts on this statement, is it still accurate?
I just got my drop checker a week ago (using kH 4 reference fluid) and over the last week I have dialed in my CO2. The plants response (pearling) is amazing and I know that I am on the right track. I'm glad I took it off the pH controller. However, as the day progresses my CO2 indicator goes from green to light green. It doesn't hit yellow, but the CO2 level is increasing as the photoperiod progresses.
If I combine his statements and my experience, it looks as though I am actually overdosing carbon (via CO2) and I should decrease my bubble count.
Question 2: Do you agree?
Question 3: Should I change my CO2 bubble count as to maintain a constant green color, while seeing a pH increase during the photoperiod? If this is actually possible to achieve ....
Question 4: If my CO2 level fluctuates from 30 to something higher, does this fluctuation still lend itself to a higher probability of the appearance of BBA? Or, is it just a fluctuation on the low end of the scale that lends itself to BBA?
Thanks so much!
Regards,
