I think its something with how the skimmer is initially started. I've had the octopus hob 100F running on my 40 breeder for about 10 months, and it took nearly 6 months for me to figure out how to get it to work properly. I'll try to explain the best that I can:
1. Fill up the skimmer with water to the top of the pump (or maybe as much as you can).
2. While holding your finger over the air inlet hose (which is connected to the silencer for mine), plug it in. This will start siphoning water in from the tank.
3. The water level in the skimmer will drop, as it gets to the bottom of the pump, release your finger from the silencer.
4. The skimmer will begin to cycle water through it, and the water level in the skimmer should increase until it submerges the pump (halfway to 3/4 submerged for mine).
5. Let it run for a minute or two.
6. Unplug it!
7. Let the water levels even out in each chamber, (so wait about 10-20 seconds).
8. Plug it back in.
Before I figured any of this out, the bubbles would barely reach the bottom of collection cup. This initializing technique helped increase the amount of bubbles so my collection cup is almost at the top, and a stable amount of bubbles are output.
There's something about getting this skimmer's siphon working first, then unplugging/plugging it back in... hope it helps.
My problem is the bubbles aren't consistent. 1 minute they will be low and then the next minute they are bubbling to much. It is skimming green and brown crud.
