“One test is worth a thousand opinions”
If you have a constant CO2 source this test is easy to run. Why not
run it and post your results? It should be interesting.
I recently ran a test with my aquarium in which I am running an
Aquaclear 300. I use two foam blocks in it and have it set at the low
flow rate. I assumed that if I kept the water level set so I get the
smoothest return possible(smallest ripples) from the filter that it
would minimize my CO2 loss. This turned out not to be true. I found
that if the return water drops about a ˝” my pH runs .1 to .2 lower.
My guess is that when the water is returning parallel to the surface I
get more surface movement and hence a greater CO2 loss.
