without this mod all the microbubbles go right in Ur sump & if u have a small
sump they make there way to the tank, one way to eliminate the microbubbles
is to use a filtersock, i don't like to use them so i came up with the elbow
design it just makes perfect sense, when i made this mod it made a
huge difference on the microbubbles going out to the sump they went
down to zero.
use the same elbows as these 1.5 u tube
u don't use the reduser on the one side the elbow slips right between
the side of the acrylic & the bulhead.
