I need something to slow down the water entering the sump to prevent micro bubbles. I have a 1.5" drain pipe going into my sump. Currently I tie a filter sock on it but it's annoying to change it.
I don't have enough room for the hanging sock as sold by some dealers.

anyone have sugguestions?
my problem is the bubbles pop and make for a lot of salt creep.
I have a durso setup from the top and changing it to another is not an option.

thanks.
