Thanks, I like to keep track of the parameters and realize the KH/Carbon and PH relation. I'm new to the CO2 and understand that the CO2 is going to alter the PH. The woman whose fish and equipment I have, told me she only ran the CO2 for two hours because the PH went from 7.4 to 7.2 and that is where my concern came from.
So, my own water is like 7.6 or a bit more, I was just wondering if I was monitoring the PH every hour, if there was any point I should become concerned. I start at 7.6 before lights come on and 12 hours later if I'm at 6.6 (I'm using random number), I shouldn't have to worry?
I'm so new to all this and trying to wrap my brains around the details now. With the plants using the o2 at night, I have a fluval 304 running and was thinking at night, I should increase the flow for more oxygen and then turn it down in the am when the co2 comes on. It my mind this makes sense, is my logic faulty?
Thanks. Just don't want to stress the fish!
