I'm going to put more in and see if it has any effect over the next few days, I have a 5lb bottle with a check valve, bubble counter and diffuser. I was also thinking of running it for longer since I run it for only 8 hours during the day. Anyway thanks for your help!
I would not. Oxygen bubbles defeat the purpose of injecting CO2. I use a circulation pump placed low in the tank and angle it slightly upwards so that I have "slight" ripples on the surface: just enough to break the surface film. You can run O2 at night if you want. Maybe use a timer.
Make sure that you do not go too much above 30 ppm. If your CO2 solenoid is plugged into a pH controller, set the pH at 7.0. If you are using a drop checker, keep a constant check on your pH until you can calibrate at the optimum level of 7.0-7.3. I would calibrate in increments. shoot for say 7.4. once that is achieved, then increase the bubble count to get to 7.2. Just don't gas too much too fast. be patient or you may "gas" your fish.
Thanks for the help, I was thinking of adding more co2 because it should lower the ph, I am going to slowly add more over the next couple days to see if I can get it to the right amountI guess I should clarify a bit. A lot of CO2 users refer to 6.8-7.0 pH as the sweet spot for CO2 injection with the spot checker turning "green". These pH readings are obtained using 4 dkh solution like this: https://www.amazon.com/dp/B01MY87WVP/ref=twister_B08X7GTPVZ?_encoding=UTF8&psc=1
If you look at the CO2 chart for 4KH and follow over to the green area, you will see that a pH window of 6.7-7.0 is green. So, it is better to have 4dkh solution in your drop checker.
If you DO NOT have 4dkh solution and taking pH readings with a test kit using aquarium water, since your KH is 8, look at 8 KH on the chart: your "optimum" CO2 level is 7.0-7.3.
Thank you! I will do that
