...update

Got the diffusers but the pump won't be here this weekend, bummer.

Since I already have a shop compressor, I've decided to procede with 15 minute thing so it'll be ready for full duty next week.


Here are the deffusers...
1mm slits, I think.


Installing the PVC...




Decided on a temporary setup using a reducer
to use a temporary 3/8", $21 air hose till I get the 1" permanent setup. I need an extention air
hose anyway...


Had to convert my tyre inflator to keep
the pressure at 5 psi. Pressure regulator on
the compressor only goes down to 60 psi...


Finally the results - a nice, stinky boil.


I'm glad I got this show on the road, coz my cat fish has been gasping for air. That's not a good sign for a bottom fish.

Will keep in touch.
