sea swirl seals are leaking air
 

so i get nuts from my sea swirl,

all in a sudden it is introducing big fat air bubbles in my tank, and not a little.

it never did this but now, I could kil the thing.

I tuck it out and found that the 2 seal ring’s are a bit worn out, so I put some Vaseline on them, but still.

any one that knows how to seal it (it is 100% the seal, no air coming from the pump, and you hear the water and air mix in the pipe of seaswirl

If the seals are worn they will need to be replaced. If they are odd shaped get an o-ring of the right diameter and cut it to length and reglue the ends together with CA glue (ie.crazy glue)
