I have had it since jan. love it so far. I take it apart about once a month to inspect/clean everything. I run mine on the forward/reverse cycle set at two minutes. Forward speed is set at 40% and reverse 80%. I also run one A impeller and one B. I mounted mine vertically as I have a cube. A rectangle tank they recommend horizontal placement. I also love the feeding mode. It shuts down for 10 minutes then restarts itself in the last mode/settings it was running at.
I'm beginning to dislike this pump now.. I'm on the last set of impellers, flow has decreased and I now have to run it 100% to even make the water move... So done with it.
Yep, same happened to me. Loved it when I got it. Ran it at 30 pct and it moved an ocean, now I'm at 100 pct and I'm about to put my other mp40 back on
