I am using a CO2 diffuser on a DIY settup. And it has been creating a fountain of Microbubbles, it started working better when I added the second gallon. My diffuser sits at the bottom of my tall tank and has no problem forming microbubbles.
Diffuser - Estone spiral V diffuser bought on amazon - The suction cup it came with sucks(not literally)!
KIV-1116 Lalvin Yeast for Winemaking
2 X 1 gallon Jug
- 2 cups sugar each
- 1/3 teaspoon Yeast
- 1/4 teaspoon baking soda
This is currently keeping my system at Approx. 14ppm
I am considering adding a 3rd gallon jug. People say DIY systems are not stable enough, well 3 Jugs cycling at different times should stop the inconsistancy. I am considering buying Pressure gauges to help keep tabs on the Yeast. For now writing it down has been working only need to start a fresh jug every 4 - 5 weeks.
I made the hole thing with 4 check valves, Standard tubing, Aquarium Silicon and drilling holes in tops of water bottle and jugs.
I ran this settup to prove you can run CO2 on larger tanks, but it might eventually end up costing me more money in sugar in the long run, so far it has been pretty darn cheap. I'll have to stop by Costco
Update: I currently have 4 1 gallon jugs for my DIY CO2 settup for my 75 gallon, This has created a fountain of microbubbles no issue it receiving pressure. I have it sitting under my AQ filter 100 or 400 whatever the series is called now flowing it right back down into my tank very happy with the settup so far.
I am still unsure if it is providing enough CO2 for my tank I have API liquid PH tester and test strips neither are very definitive I have no Idea what my Co2 PPm is. I think i'm at 7.4 ph with ~200gKh so probably 20 PPM. The issue is I was getting the same readings when I had 2 gallon jugs versus 4 gallon jugs, its definetly creating more CO2. If anyone has any Suggestions how to get a better reading, I'm considering going with a Drop checker, not sure how fine tuned those can get.
