How would I raise my ph with the co2 lowering it?

thanks

I'm happy to see you got your system up and running. It looks good!

This thread might help you with your pH question. Most likely though, you don't need to buffer your pH or KH much.

It dropped to 6.0, I think it might be because of too much yeast. thanks for the link will check it out.

Would adding a DIY unit to my 29 gallon help get rid of hair algae?

thanks a lot

p.s. sorry didn't see you in chat, I'm active in their now

Hi Guru

I also read the paper for DIY linked here: http://www.qsl.net/w2wdx/aquaria/diyco2.html#2

It 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).


I'm definitely going to do a DIY c02 application first before I try the compressed one. I feel like i'd learn so much from building this and trying.

Hi

I have a 15gl tank with plants and no CO2.After going through this thread Iam really excited to set up DIY CO2 for my tank too.

I have heard that CO2 can be relased to the tank using your powerhead filter,but dont know how....

Please clear my below queries(may look a bit foolish coz am new to this):

>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.
>How do I control the flow of CO2 and how many bubbles per second/minute need to be allowed.
>Does the CO2 flow need to be stopped during the night when the lights are off,if yes how do I do it.

Hi Ravi,

1) People diffuse CO2 straight into their filter by placing the CO2 tubing directly underneath the intake or wedged in between the intake strainer. The filter will suck up the bubbles, break them down, and will dissolve the CO2 inside the filter and spit out what doesn't get dissolved.

2) You can't control the C02 flow rate with DIY CO2. But there is no worries, with DIY CO2 expect around 1 bubble every 4-6 seconds.

3) There is no need to turn it off at night. The amount of CO2 that gets "injected" and dissolved isn't going to harm fish in any way. However if you are really concerned about too much CO2 at night, you may place an air pump and airstone on a timer to run at night, thereby degassing any C02 in the tank.

Have fun with your DIY CO2 setups! You'll love it when you see your plants grow better.

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?

Thanks

The Hagen ladder works very well, but is large and unsightly at times. Works best in 20 gallons or less.

The Nano glass diffusers and the other types of glass diffusers work well when placed under a flow, powerhead, or filter intake. This maximizes the dissolution of C02 while spreading the CO2 bubbles throughout the tank. Works best in 20-30 gallons or less (with DIY CO2).

The powerhead/siphon tube combo is another good one, which I've been prefering over the others. Dissolves CO2 well, and doesn't require much cleaning like the other two. I would purchase the Red Sea Reactor 500, since it's small. Works best in 20-25 gallons or less.



Same dissolving principle of the Reactor 500, and powerhead/siphon combos. Power Vortex Reactor at work.

Ultimately, since they all work pretty well, it's based on your preference of look and style.

i really dont understand the whole syringe bubble counter thing. can someone give me a link or explain it to me? big pictures would be great
