CO2 Diffusion Options in a big tank.
I know, I know, enough has been said, just read the other 10 posts. My question has a slightly different twist. I travel a lot so dependability, no fiddling is a must.
My tank is 84g. Seems from all I read that a reactor would be the best way to go. There are two issues with that though. One is that the cabinet space on my 320L Osaka tank is very limited. Two is that I travel for work and am usually not home during much of the week. The kids (3 and 7) and mom aren;t going to adjust, troubleshoot issues and are certain to panic if the slightest problem occurs.
So...more important than "absolute best" is thatit be as fool proof as possible. A reliable regulator/valve is definite. Question is what diffusion method will be the simplest.
Reactors/infeed lines, etc... seem to have potential for minor fiddles from what I've read here. Can't have that.
In tank diffusers I understand aren't that eficient, but a simple line to a deive in the tank, not integrated with other systems seems simple.
Eeryting needs maintenance and attention. Trying to avoid the niggles that the household won't handle when Dad's away.
Thanks in advance,
