HOB filter waterfall mod

Is it possible to mod a hob to get rid of the waterfall sound? Or is the only method to just keep the water level high enough

I don't have a picture but awhile ago, I used a small piece of acrylic that I siliconed right under the water outlet. It was slanted at a 45 degree angle and it went two inches into the water. It was basically invisible. Instead of the water going straight down, it went down on the sloped acrylic and was virtually silent.

I once put a piece of driftwood under my outlet and a nice patch of hairgrass started growing right where the flow was greatest. I kept it till it started spreading around the tank.

You can also use some silicon to glue some mesh or net stuff at the end of the waterfall

Non-abrasive nylon scrub pads work well, also adds a degree of biological surface area.



I like the NA because they are softer and more pliable. Just be sure get the ones that dont have detergent or other additives in them.

Cut to size and then silicone to the bottom edge of the filter's outlet. This one is a few months old..

(dont laugh at my salt-encrusted rim, it's a cichlid tank )

I'm not seeing how this works? The pad goes inside the filter?
