CO2 tablets ??

[BuzzDaddy21]

Has anybody used those co2 tabs with any luck?? 

I just tossed my java ferns, looking bad, tired of no results. 

Maybe I`m too impatient.

I have used them a couple times. First bottle was in my 100 gal to see if it worked. I could tell a mild growth increase in my wisteria. No pearling just better looking plant. The 2nd bottle I tried in my 2.5 and 5. It crashed both tanks at 1 tab every other day.

It did convince me to just go full high energy on my 100. I would not use them on smaller tanks with fish.
