Too much CO2, please advise
Hello all,
In my attempt to experiment with CO2 injections I have set-up a 10
gallon to see the effects. My tap water has a pH of 7.6 and a KH of 4. I am
using a AquaClear Mini for filtration and bubbling the CO2 into the intake
tube. In order to find the effects on the water I ran the CO2 (yeast method)
for a day. It dropped the pH to about 6.2, thats alot of dissolved CO2 isn't
it? I figured that it would go down after I but plants in the tank. So
today, I placed the gravel (no additional substrate yet) and the new plants
in the tank ( 3 bunches of Green Hygro, 4 bunches of Rotala, some Anachris
clippings and about 4 small Corkscrew Vals). In doing so, I replaced about 2
gallons of fresh water. When I turned on my 20w Triton and 15w Penn-Plax
lights, the plants almost immeditately began to produce bubbles (Oxygen, I
assume). First of all, I've heard about this happening, but have never
actually seen it, or hoped to achieve it. About 9 hours latter, I tested the
pH and it was still 6.2. I don't believe that there is much outgassing of
the CO2. My question is: Is my CO2 count ever going to come down? Is too
much dissolving? I want to put some algae eaters in, but I think this pH is
way to low. Any suggestions would be wonderful. Oh, I am using 1 tsp of
yeast to 1 cup of sugar.
