Using the directions on this page
, I constructed a DIY CO2 generator. I finally got all the parts necessary, and I mixed my first batch this morning. In a 20 (start-edit)
Gatorade container filled almost to top with water, I mixed 1/2 cup sugar and 1/4 teaspoon yeast; I forgot to add the baking soda per the recipe
. I used a smaller recipe since I am only dosing an AGA Mini Bow 5. Within the first thirty minutes after mixing, I was getting about 6-10 bubbles per minute.
I hooked up the tubing to the intake of the MiniBow5's HOT Whisper filter. Within a couple of hours, the plants (cabomba and ludwigia) were "pearling"! Nice!
After six hours of CO2 dosing, however, the fish were acting funny
. They had the shakes, swimming vertically and even swimming upside down. Not good! Knee-jerk reaction, I disconnected the DIY CO2 (start-edit)
from the (end-edit)
About three hours after disconnecting the DIY CO2, the fish seem
to be ok; no more erratic swimming as far as I can tell. Are there other symptoms for which I should be on the lookout? The plants are still pearling a bit, though.
I'm guessing that I did not have enough buffer/KH. I tried to get a cupful of crushed coral/aragonite from a LFS to use as buffer, but the LFS wanted to sell me a whole bag instead. I'm going to ask another LFS tomorrow for a "cupful" to place in the Whisper as buffer. Are there other alternatives for use as buffer?
Is this DIY CO2 generator too much for this 5 gallon tank? Thanks.
