Latewood doesn't say how much LK to use - at least not in the sticky, which I have printed 'cuz I'm trying his formula. The LK bottle says 10-12ml/gal. I think I'll try cutting that back to 5ml/gal like BlueBear suggested.

I'm having the same muck problems. My pump is ok, but the sprinkler heads get clogged and need to be cleaned frequently. Plain water washes the gooey crud away. I don't think you need to use alcohol.

I have an airstone in my reservoir and I still get the goo.
