Two Bottles vs. One for DIY Co2 (and other Q's)

I'm running a 16.9oz water bottle on my daughters 2gal and it works amazingly well! Now calculate the size difference from that to a 55gal, and you get about 465oz for a 55gal. That gives you about x6.8 two liter bottles. A lot of work to save money but that's what DIY is all about.

As far as diffusing, using your cannister is a good way idiot don't have a reaction chamber.

Also keep in mind you don't want any bubble wands or surface disruption because it will degass the c02 faster.

Also with DIY c02 there isn't really any need to turn off the system at night like pressurized units because you won't be reaching high enuff levels to matter.

Hope that helps.
 
I think when you get up over about 40g, the amount of mixture needing to be maintained really loses it's cost effectiveness and ends up being a chore.

I'm going to be running a test dosing with glutaraldehyde rather than diy co2 and measuring the cost/effectiveness vs a diy setup.
 
I am probably goimg to get the small pressurised setup from Foster and Smiths. It's about $100 but comes with a 2 stage regulater, bubble counter, solonoid and timer as well as a drop checker. I already have a 40 ounce bottle for my paintball gun so it would work out pretty well I think.

I am using 1 2 liter on my 20 gallon and have put a sock over the outflow of my filter so there is no surface disruption so we shall see how it goes.
 
Wow, thanks for all the feedback. It does seem like an incredible chore, for sure. I can keep up with 2 bottles, but four? :sigh: and 6.8 bottles? That's a lot.

Maybe I should do some more reading into pressurized setups that are more cost effective.
