The Official Asylum Reef Tank Thread

[OLS]

I had an interesting theory pop into me head last night. I have one of the OOOOld style Berlin skimmers,
in which you hook up a 'jet engine' to it and it makes some bubbles and maybe skims. However, all these years
I was getting bigger and bigger water pumps cause I thought with the type of venturi it had, it would only
make sufficient bubbles if it was flowing mad water. But when I re-purposed it this week, I used a comparably
tiny pump on it, and I opened up the air hose flow wide open and I was barely gettin foam. I think in
the years past, I had max flow, but I had to stop down the air injection to near zero to keep it from
overfoaming. I think once this one tunes up a bit I am gonna get good foam from max air and less than
max water flow. Sad part is although I have three different pump sizes, on a 20 gallon tank, there is not
much room for pumps. So I am sticking with lil junior.
