I look at trade offs for each method and explore each. This is the only fair method os assessment.
I've run the gambit on CO2 and DIY modifications, various methods.
They all work but have certain trade offs. I have switched out my mazzei ventui and other high powered systems for CO2 to try disc once again.
The mazzei is a bit large, requires higher pressure flow rates etc, it is also subjected to the filter clogging, all in line systems have this tradeoff/failing which can and does reduce CO2 flow into the tank.
I also did not like the noise if I added another pump, nor the electric bill increasing.
Disc have to be placed in the current, which is not always asethetic depending on design of the tank etc.
I think the CO2 mist is a very strong method, and disc, mazzei, needle or mesh wheel methods are the most effective.
These can be added in conjunction with a CO2 reactor etc or not.
CO2 is cheap, electric is not, I want the most out of my filter and flow, disc require no energy other than the solenoid valve.
So if I use another 10% more CO2, it is still well worth it for electric savings.
I still have to clean something no matter what, but this does not affect the CO2 as much and the disc is out there where I can keep an eye on it.
I've used disc and most methods several times in the past and have been CO2 reactor DIY obsessed for a decade or so.
Nutrients are rather simple and easy to address for me.
Light and CO2 are less so.
So that is where I focused most of my own effort.
Tilex bathroom cleaner works best for cleaning the disc, much better than plain bleach
