Durso Question

[Toxik]

Has anyone tried the Hofer Gurgle Buster? How has it compared to the durso or herbie? I was thinking of trying this.

Here's how my Herbie looks:





I like to have a trickle down the emergency drain. I find that there's a wider "sweet spot" like this. There's no additional sound since the surface tension of the salt water makes the bit of water going down the emergency drain stick to the walls of the PVC eliminating any dripping, gurgling or splashing.

I've completely shut down the main drain with the ball valve and the emergency drain handles it without issue. Once the amount of water exceeds a certain level in the emergency drain then I start hearing the telltale gurgling and splashing.

The Hofer is the sort of the same idea as a Stockman or Durso in that they draw in along air with the water. What makes the Herbie silent is no air is mixed in.

Ok, so I pretty much got the idea of the Herbie down pat now. Thanks guys.

Now that Im a vicarious expert on Herbies I got another query; where exactly is water getting oxygenated if the Herbie doesnt mix air in the drain pipe with the water in a turbulent fashion?

I thought maybe this would occur in abundance in the skimmer with millions of micro bubbles, is this an accurate guess? Or do I need to worry about oxygenating my water somewhere in my system if Im running a Herbie?

Also, I think I'm 99% sure Im running a Herbie now, whereas last week I was 80% sure I was running a durso haha.
