Let me preface this topic with my set up and PH Profile
50g (36x18x18) lightly planted
Fluval Planted 3.0
Fluval 407 canister
Ista PH Monitor
Aquarium water degassed = PH7
CO2 Schedule:
On 06:00. Off 13:00
Lighting Schedule:
Ramp up 09:30(PH6)-10:30 (PH5.8)
Ramp down 17:00(PH5.8)-18:30(PH5.9)
I would keep the CO2 on for longer but it just degasses to PH7 by 06:00 for the start of the CO2 schedule.
So the prevailing philosophy on this forum appears to be, and please correct me if I'm wrong, that the the target PH drop should be reached by lights on, and that it must remain completely stable for the full photo period.
So now for the bubble paradox.
I've read elsewhere that the distribution of CO2 bubbles, to the point where they make physical contact with each leaf is equally as important as the actual PH drop.
But as you can see from my PH Profile there are no undissolved CO2 gas bubbles in my aquarium for the majority of my photo period.
Further to this I've read countless posts on this forum expressing the importance of flow and circulation in regards to CO2.
Again a paradox to my PH Profile - clearly for the majority of my photo period I have reached my target PH through dissolved CO2 in the aquarium water.
A small body of water, in this case a 50g aquarium, with even a modicum of circulation, will evenly distributed any completely dissolved gas (in this case CO2), so why would circulation be an issue.
Do let me know what you think, because right now the two concepts appear contradictory, at least for my setup.
