I’m enjoying it too!
I think the starter of this was because I said light helps you dial in co2. With higher light, you can't have long ramp - it won't work because the CO2 inj. rate required over photoperiod will accumulate too fast if it gets a headstart.
Ok - I’m going to flip this one on its head, (Kind of) so bear with me. I’m still stuck on mechanics rather than benefits.
Can we agree for the purpose of this example, that light drives Co2 demand. I know other things may also contribute but let’s leave them to one side for the moment.
On that basis, light dictates plant uptake and subsequently, how much Co2 is required during photoperiod to meet that demand.
The higher the light, the more uptake, the more Co2 required.
The more Co2 we inject prior to lights on (should we choose to) the quicker we hit our desired drop and the shorter the ramp up period is.
In addition to the above, the tank has a certain amount of off gassing. The amount that is off gassed is dictated by the level of water movement/off gassing method used. (I’m guessing the amount of Co2 in the water may also impact the amount of off-gassing but I’m setting that aside too)
So the more off gassing we have, the more gas we need to maintain our Co2 level.
If we therefore combine high light and high off gassing we would need high Co2 and subsequently the ramp up period would naturally be reduced.
Regardless of this, once we have balanced our input (Co2 injection) with our output (uptake and off gassing) equilibrium is achieved.
Therefore, with the above method, the uptake demand and the off gassing method dictates the ramp up period, whatever that may be.
So is it a fact that you can’t have long ramp with high light or simply a case that, as a result of high light, ramp up periods are naturally shorter (not necessarily super short, just shorter)
I currently run lower light (new tank) and it takes 3.5 hrs of Co2 ramp up to hit 30ppm, in my 700ltr tank, by lights on. (I ramp the lights for just 30mins for the happiness of my fishies) How much higher would my light/Co2 demand have to be to naturally reduce my ramp to 30mins I wonder?
My feeling is that regardless of how much light I ran, uptake would never increase to a point where I would have to inject the level of Co2 required to get to 30ppm in 30mins.
I’m currently running more bubbles than I can count into two reactors, let’s say 20bps between them, for arguments sake. I’m sure it’s not linear but how would I hit that 30mins ‘target’? 60bps? 90bps? Or do I just lay the bottle in the tank and open it? 😳😂
Joking but you know what I mean!
Also
With your method, you eliminate ramp up by dictating high Co2 (rapid injection) you run high light but have ‘unlimited’ Co2 so no deficiency but you must surely also have to have a high level of off-gassing to ensure that Co2 levels don’t just keep increasing. How else could you guarantee that your plants use the amount of Co2 you are throwing at them by ‘dictating’ a 30 min max ramp up. They will only use what they need, the rest has to go somewhere?
