Rena micro bubblers. I suggested that Rick try these as I am getting
better results with them than I did running CO2 through the filter intake,
and
I'm getting close to 35 ppm CO2 into my tank; a drop from 8.1 to 7.2 in
water
with a KH of 16. They work great for me. Rick, you might try mixing some
cheap bakers yeast with the wine yeast. I found the wine yeast takes
longer to
get going and never gets as high a ppm but does last longer. I'm mixing a
highly recommended wine yeast with my Fleishman's. BUT, to get that 35
ppm or
so, I'm heating my yeast bottles to about 85 degrees. Even with the added
heat, the individual bottle will last 2 weeks and I just change one of the
pair
a week.


the bubbler is working fine, steady stream of fine bubbles coming out, just
nothing doing on the PH scale. I'll give the bakers yeast a try on my double
bottle glass set up on my large tank where I have yet to see a bubble in 2
days.
