I’m happy with my newest cleaning solution. The stickiness on the rubber O-rings (Vinyl Stack), I reported a while back, was due to too much cleaning solution.
After the US cleaner has rested for 5 days, upon restart I notice what looks like short fine black hair. Not a lot. I assume this is vinyl "shavings".
I finally ordered my .5 micron filter to supplement my 1 micron filter. Should arrive today. I think I’ll install it after the 1 micron filter based solely on the higher cost of the .5 filter.
Really the visual "shavings" should be taken care of by the 1 micron filter. I think the real issue is either/or a lack of proper suction or not enough volume ability to be sucked out of the tank. Maybe a larger outlet of more strategically placed outlets?
For those of you with an Elma or similar unit, how is the design in this area. Maybe, like a household sink, the water outlet should be in the center of the tank?
