CO2 Tablets - How efficient are they?

Well i've just gotten a 10g (24" x 12" x 12") aquarium about slightly more than a month ago. I've been browsing through this forum for a fair while, however, have not stumbled into anyone even mentioning about CO2 tablets.

I'm just wondering, if any of you have ever encountered such product? And if so, how efficient can they be? Pros and cons as compared to DiY CO2?

It seems to provide pretty accurate measurement -

1 tablet per 20 liter to add 5mg/L
pH value reduced by 0.2 per tablet

It normally dissolved within hours. However i find that at times, it takes an entire day before fully dissolving. Any ideas why?

Thank you so much for your time! :)

I retail co2 tablets. However I do not recommend them for anything bigger than 20l nano tank.

The ones I sell dissolve really fast. Within 5 mins in my tanks.

Now pros and cons.
Pro - they are White, clean and easy to use. They also release micronutrients as they use these salts to bind the baking soda.
Con - they are not measured quantities. There is no way you can measure the quantity of co2 being released. The co2 spikes for 5 mins and then nothing!

Overall - for someone wanting a low tech nano they are good. For someone wanting a good lush tank with specialist plants such as ug or hc... No good at all!

Thank you Frostie for that information.

I've already discarded them tablets and switched over to DiY Co2. I simply stuffed cigarette filters towards the end of the output hose and it's generating real fine bubbles similar to misting i suppose.

However, i noticed that alot of the micro bubbles are floating along the surface of the water, are they dissolved?
I have not purchased a drop checker nor any test kits due to budget reasons, tho i'm constantly monitoring my tank for any oddities and try to stay on top of things.

So im currently using the Co2 Bell method to increase contact area and diffusion. However im uncertain as to exactly how should it function? What should i be trying to achieve with the bell?

The bubbles flowing from my ciggy filter output is very small as it is, how does this method help?

I followed the advise from this link : http://www.qsl.net/w2wdx/aquaria/diyco2.html

The "bell" is the most simplest way, drill a hole, attach the hose and thats it.
As bigger the bell = as more Co2 will go into the tank.
(There is a formula around to calculate the correct area size for such bells)
You can also use more than 1bell so that the Co2 moves from Bell1 to Bell2 (second smaller pic)

Things like ciggy filter output are not necessary and it will not help anything great to improve things if it will not produce really tiny bubbles.
If you want better results, you need pressure Co2 and things like Atomizer.
