I don't even use my drop checker any more. I took a Saturday with nothing to do but home work, and kept inching the CO2 in one hour changes, when the angels headed to the top for air, I dialed it back to the previous hours setting. Mine is on a timer and I run a huge airstone at night 12 hours CO2 12 hours Airstone and a 10 hour photo period. How ever CO2 was my limiting factor for the plants, you may not need to run as much CO2....bubbles per second cant be counted, looks to be a solid stream...I don't even bother with bubble counter refills except during water changes it evaporates with in a weeks time, so every other week it gets refilled and I just use water.
