Will co2 afect the water chemistry ?
I have a little success with plants and now I want to make a co2 system. Will this affect the water chemistry. THANK YOU.

Are you doing DIY c02 with a yeast mixture ? How big is the tank your planning to inject C02 into ?

I moved this thread to the aquarium plants forum- you're more likely to get a response here.

I know that CO2 will convert to carbonic acid in the water, which tends to lower PH... If the hardness is high however, the CO2's impact on ph will be less.
Many aquariums rely on the CO2 produced by the fish and substrate- it produced plenty for most of our needs. (We use what's called 'Low Tech'.)

Yeast CO2 is never worth the effort IMO. Pressurized can be, if you want to use high light, fertilise daily, and trim your jungle twice a week.

If you have little success with plants CO2 is not a fix to plant growing. Most tanks don't even use it. I have two tanks that do and agree with redchigh that a yeast system is not worth the hassle and its limited capabilities.

More important than C02 is lighting.

Can you give more information the your current system and the plants you have tried?

If you could please give everyone your tank size, water parameters, tank stocking, plants in the tank, any furtalizers used, how often and big of water changes. All that information will help.

I have to disagree with the comments made that DIY co2 is not worth it. I made my own experiment using two 10 gallon tanks side by side. Both had fluorite as substrate and both had same livestock. Only one had DIY c02 running thru a small power head. Both had the same light that went iver both and both were dosed once a week with flourish comp. After only 3 weeks there was a great difference . I was trimming plants from the c02 tank every week(for the 2 months I experimented) where as the non c02 tank I never had to trim . I'm now experimenting 2 different yeasts (bread yeast and champagne yeast ) hopefully the champagne yeast lasts longer than 12-14 days which is what the bread yeast usually lasts me. After the 10th day I usually make a new mix and swap them over on the 11th day

They are more effective if you run two or more bottles at once, so you can keep the CO2 production steady. CO2 might be feasible in some situations with a 10 gallon tank or smaller- I won't argue that.

Any larger than a 10-20 gallon though, and it probably won't be worth the hassle. Plus fluctuating CO2 levels (from not having enough bottles), can cause more algae than not running CO2 at all.

Now that ..... I will agree with ! Lol I can't imagine filling 5-6 bottles every 2 weeks for just 1 tank ! It would cost $50 a month just on sugar ha ha

Yes of cause. CO2 can increase the acidity level of water. If the percentage of CO2 increases more than the required level, definitely it can affect the water chemistry.
