Seltzer water to raise CO2 levels?

[dtracy]

Hey all,
this is my first post, but my fish tank is currently running a very High pH at around 8.4, i dont know what is causing it to be so high, but i know dissolved carbon dioxide will lower pH by making carbonic acid, and i also know that my plant needs a higher CO2 level to survive. so i need to raise the CO2 levels in my tank. i was wondering if that would just be as simple as adding seltzer water with no sugars or other additives aside from the carbonation to the tank. does any one see any problems to doing this? i have not seen it suggested on any of the other forums, or anywhere. i looked into making a CO2 reactor, but this seems so much simpler and less expensive.

Looking for the green light on this one,
thanks!

It will work for a very short while and then you will have to add more and more and more and more and more and then it will get expensive. Soda was one of the first CO2 sources experimented with by the japanese back in the dawn of the hobby. It was found to be cost prohibitive and not an effective means of injecting CO2 and that is why we have pressurized CO2 injection now

i guess i could make a seltzer reactor the same setup as the normal bioreactor, or then i might as well use yeast

and then yeast and sugar get expensive and messy and you end up with a CO2 tanks and regulator, that is the natural progression

I have been running a lil diy co2 on one of my small tanks for about a month how and it is still producing co2 almost as much as it did the first day. I know alot of people do it this way too.
Heres what i did.
1- 2L bottle washed out. Drill a hole in the lid that will allow a tight fit for a piece of airline.
2- Piece of airline cut to length you need. feed it into the hole in the bottle cap letting it hang into the bottle bout a half inch and seal around the hole and line with silicon and let it cure.
3- add 1/2 spoonful of yeast ($1.50 for like 3 packets of it at grocery store), about 1/2 cup of sugar, and water around 100-110 degrees, and let it start producing then attach airline to a diffuser and place in tank with bottle next to tank. (i just let my co2 bubble into my filter intake and it diffuses well enough for me.

just my 2 cents.
