DIY CO2 question
i built the co2 system this morning and i've noticed that the bubbles coming out of the airstone are going inside the powerhead pump and they come out from its input, instead of pushing them out of the gravel kit and through the foam
can someone explain what i did wrong???
my setup is :
powerhead is rated for 600 liters/hour when set to maximum (as it is right now), 1/4 teaspoon yeast, 2 1/2 cups cane sugar and water, 2 x 2L bottles connected together.
thanks in advance
