I have pressurized Co2, and Im moderately new (6 months) to it.....I know that Co2 is supposed to be off at night...but....I'm wondering if I can lower the bubble count slightly, and keep it on 24.7 and still have the same results. My Ph seems to fluctuate a little too much for the livestock when its turned off at night(celebes and threadfins seem to be the most sensitive) I haven't lost any, but for the first few hours in the morning after I turn the system on, they hover at the top, The average change in Ph is from 7.4 at night and 6.9 during the day......When I have the extra $ I'll invest in one of those fancy shmancy ph regulators that hooks up to the Co2, but I'm in need of a free solution for now. So, How many bubbles per minute if I'm leaving it on 24/7? Whats the downside to leaving it on fulltime? How much will my plants suffer?
