on glassbox-design, where i originally found you, there’s a comment by Jon who sounds like the designer of this product and he says that he’s expecting a minimum 50g (heavily stocked!). i would be way under running a 29g, so i’m really worried what performance would be like in my situation.

also, your pic shows a model w/o the red acrylic/plastic. where did you purchase?

and lastly, is it worth the significant investment?

There really is something to the cone design, you can watch the bubble almost uniformly run up the sides and the turbulence in the neck is minimal, creating a nice, thick & frothy head. I too bought the Multi-use with the idea of being able to use it on 60 – 90ish gallons, and I have no reason to doubt it will rock those.

Here’s a pic from a month or so ago. The color is light, but again, the tank is lightly stocked and this color is appropriate to the stock, I think. More pics and info to come soon. Thanks:
