CO2 comparison

Hello friends

I need advise on CO2-

1. I used Sugar + Yeast + Water to make co2 for my 40 gal tank
2. I used Pressurized CO2 for my 40 gal tank

This tank is heavily planted and consists good medium lighting (7 hours/day), DIY river sand, co2 is 5bps. the co2 gets dissolved with water flow from spray bar of my sun sun internal filter 24X7

My question is which co2 mix is stronger and effective?
is it possible to use DIY Co2 for 90 gal planted tank ?

Wile possible for DIY yes, you will have a much easier time, more consistent CO2, cheaper CO2 and less work with the pressurized system. I would say it's right on the verge of un-doable DIY in a 90.

If you want to do CO2, I'd recommend going with a pressurized system. I started with DIY, as did many of us, and quickly concluded that it's just a pain in the butt. It works, but even on a 10 gallon using citric acid + baking soda to produce CO2, I was having to recharge my containers weekly. Yeast+Sugar is longer lasting I do believe, but you'll go through it quickly on a 40 gallon. I wouldn't try on a 90. If you want to run both tanks on pressurized CO2, you could either purchase or make a manifold for your regulator that would split the CO2 to each aquarium off of one CO2 tank. If you consider that route, I'd recommend a larger CO2 tank or you'll have to refill it every couple of months.

Do you enjoy DIY CO2?
I can imagine the fun of the homegrown biological route.
By saying stronger and effective:
Are you asking which bubbles are more saturated with CO2?
And are there other byproducts present?
I'd think the pressurized would be closer to pure C02 making stronger and more effective.
Also a pressurized system with a filled tank on standby would be more reliable.
Anything is possible, the question becomes one of enjoyment and practicality.
Where would you rather spend your money and time.

Thanks both of you.

My question is " Sugar and Yeast " Co2 is how pure? the gas which is produced, does it have 60/40 ratio of CO2 + Alchohol?
