i'm setoting up a tank for caridina shrimp (i'm in canada so its gonna take a while to find some) and as you can see, one of the co2 bottles is near the sponge filter and the other is on the opposite side of tank. the uptake in the left tank is much faster than the bottle further away. do you think its just boiling out the co2 or do you think the turbulence is helping to dissolve the gas into the water? cheers!
