For DIY CO2, I wouldn't be concerned about injecting to much CO2. But if you do see fish gasping then that's a sign that there is either not enough dissolved oxygen, or there is too much dissolved CO2 in the water. As for pH, just make sure it doesn't go too low...say below 6.0.i don't have a KH test kit and since it's DIY I don't have to worry too much about overdosing right? just need to monitor ph and fish gasping for breath.
The Hagen ladder works very well, but is large and unsightly at times. Works best in 20 gallons or less.It [the website] talks about the diffuser made with a powerhead and a siphon.. how would you compare it to the other diffusers mentioned?
namely, the hagen ladder, nano diffuser, the spiral one in the video, and the Spio VIII Co2 diffuser (which looks like a combination of the spiral one and a nano diffuser).
Hi Ravi,1) How do i connect the outlet to the filter that I use(picture attached) so that the filter outlet releases the CO2 in the tank using a diffuser.
2) How do I control the flow of CO2 and how many bubbles per second/minute need to be allowed.
3) Does the CO2 flow need to be stopped during the night when the lights are off,if yes how do I do it.
I am not sure but I don't think that a vinegar and baking soda mix would give you C02 production for very long. You would get an initial burst, then things would fizzle out quickly. With yeast, you may not get the same pressure immediately, but you would likely have more sustained c02 output over a longer period of time before the brew fizzles out. Also, I don't think you want to saturate your tank with too much c02 all at once. Your fish could die from the excess c02 build up over such a short period of time.Has anyone tried generating CO2 by mixing baking soda and vinegar? The amount of co2 generated is way more than the yeast recipe. Ive seen it being used to fill balloons, so I know the pressure is more.
Would having more bubbles per minute (since the CO2 is under more pressure than the yeast method) end up lowering the pH too quickly?
The first question: you are right - just scale up the quantities when you use a bigger bottle or jug.Hi,
I'm new to this, but I have a 20 gallon tank and I want to run a CO2 system through it. My question is, I have a 1 gallon syrup container, and 1 gallon is about 4 liters, so is it ok to just double your 2 liter soda bottle recipe so that it works for a gallon or is that too much that it'll burst the bottle and add too much co2 into my tank?
also, for your yeast muck catcher that you made out of a check valve and a syringe, are you supposed to fill the syringe with some water as in seen in your post? Because if so, won't the CO2 get dissolved into that water? I'm assuming that the pressure won't build enough to make it out of the water, up the tubing, and into the diffuser.
Thanks for the help guys!
