Auto dosing bio available carbon?

Has anyone setup a small scale dosing pump with a gallon jug of metricide 14 as an alternative to CO2 injection?

I recently setup CO2 myself and I realize products like flourish excel are seen as a lesser alternative but considering the hoops we jump through trying to make CO2 mesh with water chemistry it sounds like a viable alternative.

I'm just curious if anyone has done this and if so, any pros or cons of note?

So you pretty much are just comparing injected co2 vs liquid carbon, just with the liquid carbon set up on a automated dosing system?

Liquid carbon (excel, metricide, glute)
PROS: much smaller chance of "over dosing" to the point of killing fish, doesn't lower pH
doesn't off gas like co2 so you can have high surface agitation for o2

CONS: it not nearly as effectively utilized by plants, as co2 is
in the long run, it's not as cost effective compared to co2 growth results
it can actually harm some plant species

Just to name a few. Injected CO2 is pretty much the opposite of the pros and cons of liquid carbon, besides the initial costs and other details to possible malfunctions of equipment I left out.

I know the general pros and cons of using both. I'm also aware that the primary downside to "glute" based bio available carbon products is that they are more or less diluted toxins with some flora and fauna reacting very poorly to their presence.

What I'm more curious about is setting up something like metricide 14 (being the most cost effective) on an auto doser. Part of the problem with these products is that they require everyday dosing. Most of us with CO2 have a solenoid that allows us to automate the process, so an auto dosing setup seems like the most equivelant.

I have seen auto-dosing setups on here for liquid ferts. Setting up something similar for glut shouldn't be much different. I'll see if I can find something to point you in the right direction.

Mootay,

I found this old post that may help: https://www.plantedtank.net/forums/17...tml#post681001

Edit:

I found Wasserpests Master Guide to Auto Dosing. This should definitely point you in the right direction.
