Google ice cubes for cleaning RV holding tank and watch the videos. Simulated (plexiglass) tank mounted in back of a pickup show VERY LITTLE cleaning action from the ice... even when it's driven like it was stolen.Try this for breaking-up gunk in your holding tank. Open the deck pump-out fitting and dump a 10# bag of ice cubes down into the tank. Take her out for a spin, the rougher the ride the better. To help “rough up the ride” go in circles over your wake to bounce the boat, the ice cubes will bounce around inside the holding tank and help break up the gunk. The following day pump out the tank as the cubes will have melted.
Repeat again if needed.
As Peggy mentioned, toss some water in there and shake it up. That's how I get the sludge out of a tank minus the shaking. Shoot some fresh water in it and suck it back up.
