I've switched to a regulator with a solenoid; switching on a couple of hours before lights on. I set the bubble rate to the same as when I had CO2 running for 24hrs (102 BPM) and achieving a good colour in the CO2 drop checker. However, at lights on today (first since adding the solenoid) the colour was too far toward the green/blue end of the range. I upped the bubble rate to (184 BPM) a few hours ago but the colour has still not altered a great deal... I suspect it may be a good idea to replace the fluid in the drop checker but also wondering the extent to which I should expect to up the dose to achieve adequate CO2 saturation? Thanks!
