Different take on the CO2 purge...
I finally got on board with doing more purges with my Aquarium Engineering stacked reactor. I started at once a week then a few times a week, and now daily.
Few observations that need testing to verify but it seems very plausible...
1) How often you purge, at a minimum level, is most likely related to your run time ratio (on/off). I run 17 sec on 330 sec off cycle.
2) I run my purge right as lights hit full intensity (initially because that's when I'm around to make sure it's working). I strongly suspect my effluent dkh concentration drops throughout the day and night (post purge). I'm going to start it a couple hours earlier now though to ramp up the effluent concentration before full lights.
3) The side benefits of this relationship/timing (I suspect) are that my pH is less negatively impacted at night and my alk production is at it's peak when it's needed and it's lowest potency at night when not needed = super stable Alk levels in the display.
Granted this is all probably nit picky and purging more then once a day at my demand would likely reduce my on/off runtime ratio.
Could less run time could also reduce the impact on my pH or does the more acidic concentration counter act that entirely... dunno.
Thoughts?
