Extensions to HOB outlet

[gm72]

This is really easy. Save the cutouts you make on the plastic backs to your aquarium hoods. When you get a new HOB and the outlet doesn't reach down far enough (and if you don't like the sound of the waterfall or if your fish don't like the current), cut a piece of that plastic and silicone it in place to make an extension. Super easy.

i need to stop the splashing on my 55g. the aquatech is quiet, but the biowheel slops and slurps like crazy

That's one of the reasons I hate biowheels. Great bio-filtration but noisy. Not sure if you are going to be able to stop that though given the design of biowheels.
