New Pressure CO2 Installation
I recently added pressurized CO2 to my heavily planted and heavily populated 90g. I have started it out very slowly, (I believe,) at 2.5 bubbles/sec.
The PH before adding the CO2 was 7.1 and is now sitting at 6.9 and holding, according to the PH controller. The oxygen level is 10 mg/L (ppm), the same as before the CO2. The fish are fine and I was pleasantly surprised at how quickly the plants responded to the extra CO2.
I am new at pressure CO2, and am looking for some guidelines on how frequently and how far to increase the bubble count. I am running the regulator at 30 lb. I am looking for a CO2 level that will provide the most lush plant growth without stressing the fish at all.
