In your posts you used the word 'burps' I assume you mean that occasionally your filter expels a large bubble?
What do you think this bubble is made of ?
How do you think it got to be in your filter ?
Do you think the 'burped' out larger bubble is of any benefit to the tank or is it just wasting CO2 ?
I assume that the larger 'burped' out bubbles exit a spraybar/lily whatever, rise straight to the surface and dispel into the atmosphere = wasted
By 'coming out of solution' I meant by using an atomiser you are creating a solution of water and CO2 micro bubbles.
Some of the these micro bubbles collect in a filter canister and form together to make an increasingly larger bubble, which is expelled 'burped'
The remaining micro bubbles remain in solution and are circulated around your tank, because they are much smaller they don't rise to the surface as quickly thereby extending 'dwell time' and giving you the required result. Yes the drop checker is a lovely lime green and the pH drops as you desire but surely it is obvious that the same result could be achieved having the atomiser on the filter OUTLET and using less CO2 as ALL the CO2 is atomised into lovely silvery micro bubbles circulating around lush green flora. 'What you have got is what you have got' no more no less, If having an atomiser on the inlet = 1000 visible micro bubbles in tank and the occasional 'burp' you could have the atomiser on the outlet, reduce CO2 bubble rate until you have 1000 visible micro bubbles and no 'burp'
I don't doubt the method you have adopted is effective but it could be more efficient. Same end result less CO2 used.
