Thanks for the heads up. Very disappointing to hear, we really liked the simplicity and originality of this design. We hope Proline can make some adjustments to make this design work.

We appreciate the feedback and are glad to hear that you’ll be getting a replacement.

This unit jams–not as bad as classic single tube reactors–but none the less it jams and causes frustration and elbow grease to get the stones moving again. The stress and friction from 3 days worth of these jams caused my unit to form cracks in the acrylic emanating from the lower Uniseal (pump inlet).

I highly recommend to stay away from these units unless you have a VERY low cabinet and the Auger’s height saving feature is of supreme importance to you.

Holding off on running the basic 4. we were ready to jump in, but everything is going well right now …didnt want to make too many changes at once.

We’ll be trying coral snow and some of seachem’s aquavitro line. Then I’d like to try BBalance and CV.

Are you guys going to be running stones / basic 4 or just a few of the zeo products?

an auto “screw” (sounds dirty) would be great.
