How do I reduce fine bubbles coming from discharge outlet?

How long have you had it running?

Had one for a couple of years, bubbles were terrible, here is how I fixed it:

Get rid of the "T" pvc piece on the skimmer outlet.

Get these PVC pieces, slip x slip:

One 90 degree (L) piece and one 45 degree piece.

Cut just enough pvc pipe to join the fittings together (two one-inch long pieces of pvc pipe)

The output goes:

90 degree fitting (angled so it points downward at 45 degrees to the right)

then 45 degree fitting (so the output from the 45 degree fitting is horizontal with the opening 1/2 above and 1/2 below water level)

This 45 degree fitting should point towards the back right corner of the tank.

12 months. Lots of salt build up as a result.

Why does it still come with a T.

Hi ksed,

The Tee is required as the outlet has to be ventilated. Otherwise, too much back-pressure would be created.

So the bubbles float out onto the surface. I have 3 of these and I doubt that changes much. I like how JNS solved the problem for the Seaside Aquatics branded HOB they make, by using a ramp covered in sponge.

That's the best way to solve the issue. If you notice the bubbles exit through the exit pipe. If you increase the volume in the chamber eg. put a bag of activated carbon in where the intake chamber is and the volume increase therefore the larger bubble will not exit the pipe.
